Required evidence, verification status and materials actually read
Item	AVerification status	BReading scope	CReview item	DCurrent findings	EWhy unverified	FRequired materials and conditions	GFurther research
1	Met	Full text not readStored summary read	N01 · Evidence conditionIs the independent claim specifically the 2-year TG percentage change?Required	The original claim is “2-year triglyceride percentage change”. It concerns TG changes with NIASPAN ER added to LDL-targeted treatment versus a low-dose IR-niacin control strategy. The subclaim list is empty. S15 S17 S18 S19	The original manuscript and claim conditions identify the TG question. Clinical events, LDL and other formulations are outside it.	The original claim linked to the AIM-HIGH question elements.	Compare manuscript and trial identities; separate independent claims when question elements differ.
2	Met	Full text not readStored summary read	N02 · Evidence conditionIs the chemical form, formulation and route actually oral NIASPAN ER tablets?Required	Retained material specifies oral nicotinic-acid NIASPAN extended-release tablets. It excludes nicotinamide and inositol hexanicotinate; the intervention is not a B-complex product. S15 S17	Chemical form, formulation and oral route are specified. This does not establish the same effect for generic B3 products.	Product formulation, ingredient and route records.	Match product name, chemical form and formulation across drug documents and trial records; analyze other products separately.
3	Met	Full text not readStored summary read	N03 · Evidence conditionIs the target dose of the selected add-on strategy verified?Required	The NIASPAN ER target was 1500–2000 mg/day. This is the add-on strategy range in selected tolerators, not a verified individual actual dose or optimal dose. S15 S17 S19	The target dose is specified in the claim conditions and original scope. Individually achieved dosing is not thereby verified.	Target titration plan and individual actual dosing/adherence records.	Trace arm-specific doses, titration and dosing histories to distinguish target from actual dose.
4	Met	Full text not readStored summary read	N04 · Evidence conditionDoes the control strategy contain low-dose IR niacin?Required	The control contained IR niacin 50 mg/tablet, totaling 100–150 mg/day. This is not NIASPAN monotherapy versus no treatment. S15 S17 S19	Control composition and dose identify the actual comparison. Do not relabel it a wholly inactive placebo.	Control-tablet composition, dose and masking plan.	Compare control composition, tablet count and dose with the original plan and intervention records.
5	Met	Full text not readStored summary read	N05 · Evidence conditionWas background treatment titrated to the same LDL target in both groups?Required	Both groups titrated simvastatin 40–80 mg/day±ezetimibe 10 mg/day to LDL-C 40–80 mg/dL. Actual background dosing was not fixed identically, so this is a strategy comparison. S15 S17 S19	The manuscript clearly describes target-treatment strategies. It does not establish identical individual fixed background doses.	Background-drug targets, arm-specific titration and actual doses.	Compare target treatment, co-treatment changes and adherence by arm; define the effect as a strategy contrast.
6	Met	Full text not readStored summary read	N06 · Evidence conditionAre the selected ASCVD/low-HDL population and entry TG criteria verified?Required	Participants were adults age 45 and older with established ASCVD and low-HDL/residual dyslipidaemia. Entry TG was >150 and <400 mg/dL off statins, or >100 and <400 mg/dL on statins. S17 S18 S19	The sources distinguish population and entry TG ranges. Do not generalize to all adults with high TG.	Eligibility/exclusion criteria and actual recruited-population characteristics.	Compare eligibility with baseline characteristics and assess directness for other high-TG populations.
7	Met	Full text not readStored summary read	N07 · Evidence conditionIs selection through a prerandomization tolerability run-in verified?Required	Randomization selected people who tolerated a 4–8-week niacin run-in. This is not the same safety population as all people starting treatment. S17 S18 S19	The population, duration and safety records verify tolerator selection. Numbers excluded during selection are not thereby verified.	Run-in participation, reasons for exclusion and flow into randomization.	Review prerandomization flow and exclusion reasons to distinguish selected participants from all starters.
8	Not reported	Full text not readStored summary read	N08 · Evidence conditionAre baseline diagnostic values for nutritional niacin deficiency reported?Supplementary; required for deficiency-subgroup interpretation	This was not a trial selected for nutritional niacin deficiency. The historical record states that deficiency diagnostic values were not reported within the source material used. S17 S18	Nonreporting is limited to the accessed scope. It does not establish universal nondeficiency, no subgroup benefit or worldwide absence of data.	Baseline niacin-deficiency diagnostic criteria and measurements.	If deficiency was defined and measured, link it to prespecified effect-modification analyses.
9	Unverified	Full text not readStored summary read	N09 · Evidence conditionIs the chemical ingredient’s manufacturing origin verified?Supplementary; required for claims of identical manufacturing origin	Nicotinic acid is a chemical entity, so a botanical part is inapplicable. Actual manufacturing origin remains unverified in the original claim conditions. S15	Chemical identity is verified, but evidence establishing manufacturing origin is unavailable in the retained scope.	Product raw-material and manufacturing-origin documents.	Trace ingredient identity and trial product through manufacturing records; separate claims of equivalent products.
10	Unverified	Full text not readStored summary read	N10 · Evidence conditionIs total niacin exposure, including diet and tryptophan equivalents, verified?Supplementary; required for total-exposure interpretation	The trial add-on dose is verified, but total niacin intake including diet and tryptophan equivalents is unconfirmed. S17	An add-on strategy dose alone cannot establish total nutritional exposure.	Measurements of diet, concomitant products and tryptophan equivalents.	Separate individual add-on dosing from other intake sources; trace total exposure and compare co-treatment differences.
11	Partly verified	Full text not readStored summary read	N11 · Evidence conditionAre randomization and masking details sufficiently verified for the TG comparison?Required	Historical body-text extraction records central Internet allocation and double blinding, using low-dose IR niacin for masking. The summary does not verify all sequence-generation/concealment details or masking success. S17 S19	Some allocation/masking methods are verified, but details and actual success assessments remain incomplete.	Sequence generation, central allocation, masking procedures and masking-success assessments.	Compare planned and reported allocation/masking procedures at the level of the outcome.
12	Partly verified	Full text not readStored summary read	N12 · Evidence conditionAre TG measurement procedures and conditions sufficiently verified?Required	An objective blood-TG marker and 2-year percentage change from baseline are verified. Fasting sampling, reagent/laboratory versions and detailed standardization were not verified in this retained summary. S15 S17	Outcome type and time are verified, but measurement procedures remain incompletely specified.	TG sampling, fasting, laboratory, reagents and measurement procedures.	Compare measurement timing and methods across groups using the original laboratory plan and records.
13	Met	Full text not readStored summary read	N13 · Evidence conditionAre the 2-year TG assessment, approximately 3-year trial and prerandomization period distinguished?Required	The page concerns 2-year TG percentage change. Trial stopping after approximately 3 years and the 4–8-week prerandomization run-in are separate periods. S15 S17 S18 S19	Claim conditions and results distinguish the periods. Persistence outside 2 years is not established.	Assessment, trial-stopping and run-in timelines.	Link each outcome visit to its timeline and compare changes for that visit only.
14	Met	Full text not readStored summary read	N14 · Evidence conditionAre the page TG endpoint and the trial’s 1st (primary)/3rd (tertiary) hierarchy distinguished?Required	The page endpoint is 2-year TG percentage change. The trial 1st (primary) was a cardiovascular composite; lipids were 3rd (tertiary) protocol objectives. S17 S19	The source explicitly distinguishes the marker and trial hierarchy. Do not turn TG into 1st (primary) clinical-event success.	Endpoint hierarchy in the original protocol and actual reports.	Compare protocol-version hierarchies with reports while keeping markers and events as separate questions.
15	Met	Full text not readStored summary read	N15 · Evidence conditionAre the reported changes and direction verified for the same 2-year TG outcome?Required	Retained AIM-HIGH2-year TG changes from baseline were ER −28.6% and control −8.1%. Retain the reported decreases without importing another lipid’s figures. S15 S17	The arm-level values match the retained calculation and core evidence for the same 2-year TG outcome. This differs from verification of a precise between-group estimate.	Concurrent arm-level TG values from the original table/body text.	Match arm values to the same outcome, time and population; retain opposing findings as well.
16	Unverified	Full text not readStored summary read	N16 · Evidence conditionIs a formal adjusted between-group TG estimate verified?Required	Historical −20.5 percentage points subtracts reported −28.6% and −8.1%. The calculation record explicitly excludes an adjusted causal mean difference, mg/dL difference, ARR or NNT; a formal adjusted TG effect remains unverified. S15 S17	Descriptive arithmetic is recorded, but the formal adjusted between-group effect asked about remains unverified.	TG analysis model, adjustment variables, formal estimate and dispersion.	Define the model’s strategy contrast and review it separately from descriptive arithmetic.
17	Unverified	Full text not readStored summary read	N17 · Evidence conditionIs the mean/median estimator for TG percentage change verified?Required	The original calculation records the mean or median estimator for TG percentage change as unconfirmed. S15 S17	Percentage-change values are available, but evidence defining their mean/median estimator is unavailable.	The original definition of aggregation/estimation for TG percentage change.	Compare arm-level calculation and aggregation definitions in the original statistics section and tables.
18	Unverified	Full text not readStored summary read	N18 · Evidence conditionAre the actual arm-specific analysis denominators verified for 2-year TG?Required	Randomization included 3414 participants,1718 versus 1696. The original denominator explanation and evidence explicitly state that these are not verified 2-year TG analysis counts. S15 S17	Randomized denominators are known, but the actual 2-year TG analysis denominators cannot be established.	Arm-specific 2-year TG analysis n, visit attendance, exclusions and flow.	Trace randomization, outcome visits, valid measurements and model-analysis denominators as separate steps.
19	Unverified	Full text not readStored summary read	N19 · Evidence conditionAre TG missing-data handling, analysis population and effect of interest verified?Required	Details of 2-year TG missing-data handling remain unconfirmed. The source states that event-ITT wording does not prove a lipid ITT analysis without missing data. S17	Event-analysis terminology alone cannot identify the TG analysis population or missing-data handling.	TG missing-data methods, model, analysis population and sensitivity analyses.	Link missing/post-discontinuation outcomes to models and examine interpretations under different missingness assumptions.
20	Unverified	Full text not readStored summary read	N20 · Evidence conditionAre the TG between-group CI, change-score SD/SE and precision inputs verified?Required	The original calculation’s standard error, change-score SD, degrees of freedom, confidence level and interval are all unrecorded. A bounded record notes absent matching dispersion/TG between-group CI in the accessed regulatory tables; do not substitute a cardiovascular HR CI. S15 S17	The relevant TG interval/dispersion inputs are unverified. This does not claim nonreporting throughout an unread original paper.	TG between-group CI, change-score SD/SE, degrees of freedom, confidence level and analysis n.	Match TG estimators to dispersion in original tables/statistical methods; reject intervals from different outcomes as substitutes.
21	Unverified	Full text not readStored summary read	N21 · Evidence conditionCan TG importance thresholds be compared with a reported interval?Supplementary; required for importance/clinical-benefit interpretation	The source retains the TG decrease with EX(a) because its between-group CI/SD were unconfirmed; it did not relabel it E0 or below MCID. No context-validated TG importance threshold/interval is newly established here. S15 S17	Reported decreases alone cannot establish importance-threshold attainment or clinical-event benefit. The original EX/grade are historical quotations.	Context-specific TG importance criteria, a formal effect interval and clinical-outcome links.	Compare importance criteria and intervals separately; assess clinical events through direct event-trial findings.
22	Partly verified	Full text not readStored summary read	N22 · Evidence conditionIs TG plan/analysis/timing agreement verified from initial registration to final report?Required	The archived protocol is Amendment 6 dated 2011-06-01. Lipids are 3rd (tertiary) objectives and the event 1st (primary) has an amendment history. The historical ClinicalTrials.gov record did not render; complete reconciliation with initial registration is not claimed. S17 S19	The amended protocol and some hierarchy are verified; complete comparison from initial registration through final TG analysis remains incomplete.	Initial registration history, all relevant protocol/SAP versions and final TG reporting.	Compare endpoint, time and analysis changes chronologically across versions to assess agreement.
23	Met	Full text not readStored summary read	N23 · Evidence conditionAre cardiovascular 1st (primary) failure and early stopping kept within their interpretation boundaries?Supplementary; required for clinical-event interpretation	The retained manuscript states cardiovascular 1st (primary) failure and early stopping. Keep the TG decrease as a separate marker observation without turning it into clinical-event prevention. S15 S17 S19	Retain unfavorable 1st (primary) findings/stopping separately from the selected TG question. No new clinical-event effect size is calculated.	1st (primary)-event findings, reasons for early stopping and links to TG results.	Review each outcome, analysis and time separately; do not merge discordant marker/event findings.
24	Met	Full text not readStored summary read	N24 · Evidence conditionDo 25.4% versus 20.1% refer to study-drug discontinuation?Supplementary; required for adherence/safety interpretation	The reported 25.4% versus 20.1% concern study-drug discontinuation. They are not follow-up attrition,2-year TG missingness or specific adverse-event rates. S17	The safety record and C17 correction clearly classify the percentages. They do not establish complete follow-up status.	Original arm-specific drug-discontinuation reasons, follow-up retention and missing-test tables.	Link follow-up/measurements after drug stopping; examine adherence and missingness separately.
25	Partly verified	Full text not readStored summary read	N25 · Evidence conditionAre harm-collection methods and event-specific denominators verified for the same exposure/population?Supplementary; required for comparative-harm/frequency interpretation	The FDA 2020 source records pharmacological-regimen harms including flushing and increased liver enzymes, glucose and urate. The current summary does not provide every AIM-HIGH event definition, arm count, time denominator or collection procedure. S15 S17	General harm types and source are verified, but within-trial event-specific comparisons/denominators remain insufficiently verified.	Trial AE collection plan, event-specific arm counts, duration, discontinuation reasons and regulatory documents.	Compare event definitions, active ascertainment and valid follow-up denominators to distinguish signals from comparative frequencies.
26	Partly verified	Full text not readStored summary read	N26 · Evidence conditionAre the specific tests and conditions for laboratory interference verified?Supplementary; required for laboratory-interference interpretation	The manuscript records specific laboratory interference in FDA 2020 Section 7.6. This retained summary does not verify specific tests, every platform, interference magnitude or a universal stopping interval. S15	The interference source/location is verified, but specific measurement conditions remain unverified.	Section 7.6 tests, interference direction, exposure and measurement conditions.	Compare test-specific interference by platform, reagent and exposure; separate interference from biological change.
27	Unverified	Full text not readStored summary read	N27 · Evidence conditionIs safety directly verified for all starters, long-term use or other doses?Supplementary; required for safety-scope extensions	The 4–8-week tolerability run-in limits generalization to all starters. Fixed FDA 2020 warnings do not establish safety across every dose, long-term use or vulnerable population. S15 S17 S18	Selected-population records and general warnings cannot establish the extended safety scope.	Direct harm data for run-in exclusions, unselected populations, other doses and long-term use.	Study exposure, follow-up and harms in unselected starters separately and compare them with the selected population.
28	Met	Full text not readStored summary read	N28 · Evidence conditionAre the reports linked to the same AIM-HIGH study family?Required	The direct core evidence is AIM-HIGH-NCT00120289. S15’s AIM-HIGH section, S17 trial paper, S18 official archive and S19 protocol are different materials from the same family. S15 S17 S18 S19	Study name, registration, titles and used locations identify the same family. Do not count the reports as independent replications.	Trial identity, registration number, report titles and links between trial materials.	Map reports to studies, outcomes, times and analyses to avoid double-counting citations within the same family.
29	Unverified	Full text not readStored summary read	N29 · Evidence conditionIs there an independent study family replicating this exact TG strategy comparison?Supplementary; required for independent-replication claims	The direct evidence and references concern the same AIM-HIGH family. Trials in manufacturer tables are not R2 without verified independent authors/funding; other lipids or durations are not replications of this TG comparison. S15 S17 S18 S19	A separate independent family for the exact TG comparison was not verified within the retained scope.	Independent trial identities, arm-specific TG findings, population and funding records.	Classify directness by study family, separate different comparisons and assess replication/heterogeneity.
30	Met	Full text not readStored summary read	N30 · Evidence conditionAre funding, product supply and reported analysis involvement identified?Supplementary; required for independence interpretation	The retained record identifies mixed NHLBI/Abbott support and product supply. Reported sponsor analysis non-involvement does not imply I2. I1 quotes the historical verdict. S17 S19	The bounded reported support, supply and analysis involvement can be identified. Complete independence is not newly certified.	Funding, product supply, author interests and analysis-role documents.	Separate funding, drug supply, design, analysis and publication roles when comparing independence.
31	Unverified	Full text not readStored summary read	N31 · Evidence conditionDoes comprehensive searching, including unpublished trials, rule out selection/publication gaps?Supplementary; required for claims of overall evidence completeness	The original 2026-09-14 review used web indexes, a provided 3081-record index, related originals and direct publisher/FDA/NHLBI material. Exhaustive PubMed/unpublished-trial searching is not claimed. New searches in this work:0. S15 S17 S18 S19	A bounded search record exists, but comprehensive searching or exclusion of publication bias is unverified.	Original search strategy, selection records and unpublished/registered-result lists.	Use reproducible question-specific searching, family linkage and selection to review missing reports/selected results.
32	Met	Full text not readStored summary read	N32 · Evidence conditionAre original search/review dates distinguished from the retained-record review?Required (verification-scope record)	The original search cutoff is 2026-09-14 and the original verdict review date is also 2026-09-14. The retained-record review date is 2026-10-05. Dedicated evidence-cutoff and reference-specific access-date records are absent. S15 S17 S18 S19	Actual date records and their absence establish the event-specific scope. Do not fill report-specific access dates from a global date.	Original date fields, individual access histories and current reading receipts.	Distinguish search, review, access, freeze and application as different dated events.
33	Met	Full text not readStored summary read	N33 · Evidence conditionAre retained-summary reading, unread external originals and historical access levels distinguished?Required (reading record)	Actual reading concerns the retained summary. Historical records describe S15 regulatory PDF/selected-table screenshots, S17 publisher-indexed body text with unrendered tables, S18 official archive HTML and S19 protocol PDF. External materials were all unattempted, unacquired and unread in this work. S15 S17 S18 S19	The narrow reading-record condition reflects actual actions. Current external content verification is not thereby complete.	Current reading receipts and reference-specific material types, URLs and historical access records.	Match access, acquisition, reading and locations to accurate reader badges and links.
34	Met	Full text not readStored summary read	N34 · Evidence conditionAre direct TG locations distinguished from other lipids and unavailable shared-correction references?Required	Direct TG locations are S15 Section 5.1/AIM-HIGH, printed pages 4–5, and S17 Lipid Levels. C11 combines TG/LDL arithmetic; C12 has shared Table 3 wording. C14’s L128 and C16’s S16/LDL −14%/duration discrepancy are not inherited as the direct TG bibliography’s 4 sources. S15 S17	The boundary between direct TG locations, other lipids and unavailable references is identified. Do not substitute another LDL/Table 3 analysis as this TG result’s location.	Actual TG locations, full shared corrections and reference-specific identity records.	Compare correction-specific endpoint, time and source attribution; retain other-question values/unverified references separately.
35	Unverified	Full text not readStored summary read	N35 · Evidence conditionAre the latest current prescribing document and recommendations verified?Supplementary; required for current-prescribing interpretation	The FDA document used was revised 09/2020. The latest label/current prescribing guidance was not verified in this work; research doses are not personal dosing instructions. S15	A fixed historical document does not establish verification of the current version.	Current prescribing-document version, amendment history and prescribing guidance.	Compare versions while separately recording actual access/dates, administrative facts and clinical results.
36	Unverified	Full text not readStored summary read	N36 · Evidence conditionAre other formulations, high-TG populations, persistence beyond 2 years and optimal dosing directly verified?Supplementary; required for extension claims	The findings are limited to AIM-HIGH tolerators, NIASPAN ER add-on versus low-dose IR control and 2-year TG. Generic B3, other formulations, all high-TG populations, optimal dose and persistence beyond 2 years are not directly established. S15 S17 S18 S19	The source limits generalization outside its scope. Do not delete the selected-question decrease or reclassify it as effect 0.	Original comparative TG studies by formulation, population, dose and long-term duration.	Define each extension question separately; review direct comparisons, effect modification and persistence.

Assessment scope

Stored-material review date: 2026-10-05
Original evidence review date: 2026-09-14
Scope actually checked: Retained Korean/English summaries and case-specific condition/application records. Full papers, supplements, registrations, plans and original data were not read.
What the dates mean: The original search/verdict review date is 2026-09-14 and the case-record review date is 2026-10-05. Historical access dates for individual references are unrecorded. Access levels below are historical records; external access, acquisition and reading were not attempted in this work.
Population: Adults ≥45 with established ASCVD and low-HDL/residual dyslipidaemia tolerating niacin run-in. Entry TG >150 and <400 mg/dL off statins or >100 and <400 on statins. Not a nutrient-deficiency treatment cohort.
Ingredient, formulation and route: Nicotinic acid (prescription NIASPAN ER tablets added to LDL-targeted statin therapy)
Dose: 1500–2000 mg/day; control includes IR niacin 100–150 mg/day
Comparator: Both groups used simvastatin 40–80 mg/day±ezetimibe 10 mg/day for LDL-C 40–80 mg/dL. Control contained IR niacin 50 mg/tablet (100–150 mg/day). Actual background doses were titrated, so this is a treatment-strategy contrast, not identical fixed background dosing.
Measured outcome: Reported TG percentage change from baseline at 2 years: page endpoint. Trial 1st (primary): cardiovascular composite; lipids were a protocol 3rd (tertiary) objective.
Duration: 2-year lipid assessment; trial stopped early after approximately 3 years; 4–8-week run-in before randomization
Questions outside this scope: At 2 years in AIM-HIGH, reported triglyceride changes were −28.6% with the ER-niacin strategy and −8.1% with control, an arithmetic contrast of −20.5 percentage points. This is not cardiovascular-event prevention or evidence for every formulation and dose in all hypertriglyceridaemia. [S15; S17]; 3414 participants and 1718/1696 are randomized counts; the 2-year TG analysis denominator is unverified. The historical arithmetic contrast −20.5 percentage points is not a formal adjusted mean difference, mg/dL difference, ARR or NNT. The mean/median estimator, TG CI, SD and missing-data handling also remain unverified.; This pharmacological regimen has flushing, liver-enzyme, glucose/urate and specific laboratory-interference risks. Study-drug discontinuation of 25.4% versus 20.1% is not loss to follow-up. The 4–8-week tolerability run-in limits safety generalization to all starters. Safety details are from the fixed 2020 FDA source, not new current prescribing guidance. Research doses are not personal dosing instructions. [S15:safety; S15:interference; S17:discontinuation; S18:runin]; Retain original C, 46, Caution, B/S/R1/I1/EX/B1/CX and the historical grade-revalidation record. No new scoring was performed. Do not extend to generic B3, other formulations, deficiency correction, all high-TG populations, optimal dose, persistence beyond 2 years or personal prescribing.

S17 · AIM-HIGH Investigators. Niacin in Patients with Low HDL Cholesterol Levels Receiving Intensive Statin Therapy

Official source

Material type: Historical NEJM publisher-indexed body text; tables and supplementary dispersion not rendered
Materials actually read: The retained Korean/English summaries and case-specific condition/application records were read. External abstracts, full texts, registration, protocols and analysis plans remain unread; access was not attempted.
Findings recorded in the stored summary: Retained historical record: AIM-HIGH was a multicentre randomized double-blind target-treatment strategy comparison; 3414 randomized, 1718/1696, with actual 2-year TG analysis n unconfirmed. NIASPAN ER 1500–2000 mg/day versus control containing low-dose IR 100–150 mg/day was added to LDL-targeted statin±ezetimibe titration. The reported 2-year TG −28.6% versus −8.1% is not a formal adjusted effect or CI. Retain cardiovascular 1st (primary) failure, early stopping and study-drug discontinuation 25.4% versus 20.1% separately. NHLBI/Abbott mixed support and product supply do not become independent funding because sponsor analysis non-involvement was reported. Tables and supplementary dispersion did not render during historical indexed-body access.
Record level: Retained records of the same study. External originals were not revalidated in this work; retain each material’s historical access limitations.
Study overlap and independent replication: S15 AIM-HIGH regulatory clinical data, S17 direct trial report, S18 official archive and S19 amended protocol belong to the same AIM-HIGH-NCT00120289 family. Do not count the reports as independent replications or sum participants. No new overall unique-study or participant total is provided.

Application exceptions: Approval differs from proof of clinical efficacy; unverified currency does not erase historical records.
Referenced methods: Existing method principles distinguish population, formulation, dose, time, target-treatment comparator, lipid measurement, denominators, missingness, between-group estimates, intervals, plans, report relationships, funding and harms. Detailed conditions are Chamgap’s own application; they do not impose adjusted analysis on every randomized comparison.

N36 · Are other formulations, high-TG populations, persistence beyond 2 years and optimal dosing directly verified?

Current findings: The findings are limited to AIM-HIGH tolerators, NIASPAN ER add-on versus low-dose IR control and 2-year TG. Generic B3, other formulations, all high-TG populations, optimal dose and persistence beyond 2 years are not directly established.
Verification status: Unverified
Materials actually read: The retained Korean/English summaries and case-specific condition/application records were read. External abstracts, full texts, registration, protocols and analysis plans remain unread; access was not attempted.
Why unverified: The source limits generalization outside its scope. Do not delete the selected-question decrease or reclassify it as effect 0.
Reason for missing information: Comparative extensions by formulation, population, dose and long-term duration remain unverified.
Required materials and conditions: Original comparative TG studies by formulation, population, dose and long-term duration.
Materials to obtain first: Original comparative TG studies by formulation, population, dose and long-term duration.
Further research: Define each extension question separately; review direct comparisons, effect modification and persistence.
Remaining uncertainty: Comparative extensions by formulation, population, dose and long-term duration remain unverified. No new effects, intervals, denominators, incidence rates or grades are calculated or adjudicated.
Conditions for verification: Check direct comparisons for formulations, populations, doses and times outside the selected question.
Why this condition is needed: Needed to avoid extending a fixed-question result across all formulations, populations, doses and durations.
Application exceptions: Do not require every extension study for the narrow TG question.
Referenced methods: Existing method principles distinguish population, formulation, dose, time, target-treatment comparator, lipid measurement, denominators, missingness, between-group estimates, intervals, plans, report relationships, funding and harms. Detailed conditions are Chamgap’s own application; they do not impose adjusted analysis on every randomized comparison.
