## Assessment scope

- Population: The current preserved summary concerns an MRI crossover trial in nonalcoholic fatty liver disease: 41 participants, 36 completed. Do not transfer them to verified populations/event denominators for clinical cirrhosis, hospitalization or death. Clinical disease stage, baseline risk, recruitment/group-specific analysis/observation and censoring/missingness remain unverified without direct material.
- Ingredient, formulation and route: The direct intervention/comparison for the selected clinical outcome is unverified. Link only MRI exposure/comparison context from the original quercetin 500 mg/placebo crossover; do not present it as a dose or method with verified clinical benefit. Product/duration, actual exposure/adherence/concurrent treatment and subsequent strategies are unverified; no new intake or treatment guidance is created.
- Dose: 12 weeks and crossover after a 4-week washout are MRI trial conditions, not verified treatment/assessment periods for clinical disease. Direct clinical exposure, dose/duration, long-term follow-up and discontinuation are unverified; no new duration/dose conversions are performed.
- Comparator: The original double-blind MRI placebo crossover and reported ITT do not verify direct clinical disease allocation, comparison or analysis. Control, allocation/adjudication, concurrent management/treatment, models/missingness and actual units in clinical trials/endpoints are unverified.
- Measured outcome: The selected existing ? grade/note records that this trial did not test cirrhosis, hospitalization or death. Definitions/adjudication, events/denominators, timing, between-group effects/CIs/P values, prespecified important differences and power for these clinical endpoints are unverified. MRI 11.5%±6.4→9.6%±5.8, placebo change −0.1%±2.6, P=.013, adjusted P=.028 and weight changes/correlation are other measures, not clinical estimates/effects. Do not turn untested outcomes into zero effects/events, safety certification or confirmed null effects.
- Duration: Direct clinical disease follow-up/assessment windows, cumulative/recurrent events/hospitalization, censoring/death and follow-up material are unverified. Distinguish original 12-week MRI/crossover from long-term testing of cirrhosis, hospitalization or death. Do not invent follow-up reports/numbers.
- Questions outside this scope: New effect/change/response-rate/CI calculations or arbitrary %/%p corrections from MRI baseline/final values, placebo change, original approximate −1.9 percentage points/P values/± quantities and sample sizes; Summing two crossover periods/the same participants as new independent trials/participants, or deriving hypothetical total duration/exposure from 12 weeks/4 weeks; Filling an ITT account with unverified observed denominators, imputation models or an all-completer population; Turning weight correlation and MRI benefit into confirmation of direct hepatic causation/separated mediation, or calculating new direct effects; Reusing MRI/liver-enzyme/other secondary outcomes as improved cirrhosis/hospitalization/death, or exactly zero clinical effects/equivalence; Inheriting historical CI/funding checking in abstracts/public tables/full text as current whole external-document reading/review; Turning undisclosed manufacturer support, institutional affiliations/no-COI declarations and original I2 into absence of each support item/current independence verification; Turning original safety non-reporting/nonsignificance and rare-harm limitations into zero harms or treatment-safety certification; Creating currently absent clinical original reports/registration/follow-up materials or invented citations/values; Inheriting parent scores/axes and historical cross-checking as subclaim scores/current review/external reading; New calculations, hypothetical values, effects/CIs, grades, independence certification or product-intake/diet/activity/testing/treatment implementation guidance

Materials actually read: Summary read; external material unread  
Findings recorded in the summary: The preserved result of this report is the MRI surrogate 11.5%±6.4→9.6%±5.8 versus placebo change −0.1%±2.6; P=0.013, adjusted P=0.028. These are not effect values for the selected clinical cirrhosis, hospitalization or death outcomes. Preserve the existing ? grade/untested-outcome note and unverified direct clinical definitions, populations, events/denominators, duration/estimates/CIs and plans.  
Record level: Outcome wording in the stored summary  
Independent replication: S01 Li 2024/ChiCTR2100047904 is a single double-blind placebo-controlled crossover trial in nonalcoholic fatty liver disease, with 41 randomized and 36 completed. Distinguish original quercetin 500 mg/day, 12-week intervention and crossover after a 4-week washout from unverified actual sequence/period/exposure and ITT/observation/missing-data models. Quercetin-period MRI 11.5%±6.4 to 9.6%±5.8, original approximate −1.9 percentage points, placebo change −0.1%±2.6, P=.013 and adjusted P=.028 are original surrogate results, not new calculations. Do not arbitrarily correct %/%p wording; retain gaps in the type of ± quantity, between-treatment CI/important difference and original period/within-person estimates. Weight changes −1.5±2.6 kg versus −0.2±1.8 kg, correlation with MRI reduction/unseparated direct hepatic effects, nonsignificant liver enzymes/other secondary outcomes and untested clinical cirrhosis/hospitalization/death are distinct outcomes. Do not sum the same participants/arms, crossover periods, MRI/weight/liver enzymes, citations or sibling sheets as new independent trials/participants. Do not create follow-up reports/clinical effects or inherit original R1/I2 and historical abstract/public-table/full-text checking accounts as current review/external reading. Report/material-slot counts are not unique clinical trial/participant/independent-replication totals; no new sums or independence certification are performed.
