Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect.

## Assessment scope

- Population: Adults with metabolic syndrome continuing usual risk-factor care. The retained record distinguishes 65 enrolled from 55 analyzed.
- Ingredient, formulation and route: Oral aged garlic extract (AGE) capsules as an add-on. Product name, study batch and exact SAC specification remain unverified.
- Dose: AGE 2,400 mg/day. Details of actual intake, capsule count and adherence remain unverified.
- Comparator: Matching placebo plus usual risk-factor care. Original material on placebo composition and changes in background care remains unverified.
- Measured outcome: Change in percent low-attenuation coronary plaque volume (%LAP) on CCTA. A prespecified LAP-only primary (1st) outcome hierarchy remains unverified.
- Duration: About 12 months; CCTA imaging interval 354±41 days. The statistical meaning of ±41, such as SD or SE, remains unverified.
- Questions outside this scope: Total plaque, noncalcified plaque and dense calcium are separate imaging endpoints; the null descriptions in the retained record are preserved.; The finding is not extended to plaque elimination, myocardial-infarction prevention or reduced mortality.; Other garlic formulations, other AGE products and isolated SAC are not treated as the same intervention.; The unidentified diabetes background reference is not added as a new report or independent replication.; Effects of AGE combined with B vitamins, folate and L-arginine are not transferred to AGE alone.; Optimal dosing, persistence after stopping and additional subgroup effects are separate from the current narrow question.; General caution is not converted into bleeding-event counts, comparative risk, causality or confirmation of overall safety.

Record level: These are reported imaging-surrogate values, with group %changes and the adjusted regression coefficient kept distinct. The exact %denominator, meaning of ±, β unit, analysis set, prespecified hierarchy and full ITT remain unverified.  
Independent replication: The retained evidence and citation link to a report by Matsumoto2016. Group changes and adjusted β are different analysis layers for the same imaging endpoint. Unique-trial counts, participant totals and independent replication remain unverified.

| Material | Public availability | Access status | Actually read | Notes |
|---|---|---|---|---|
| PubMed bibliographic/abstract index | Bibliographic link retained; external material unread | External access not attempted; not acquired | Not read | This is the PubMed link from the retained citation. The current response, bibliographic identity, abstract content and public access were not checked. Matsumoto2016 is a report linked in the retained summary. External abstracts, full texts, registration, protocols and analysis plans were not checked in this conversion, and independent clinical validation was not performed. The date is the original check date in retained summary and condition records. The retained verdict’s evidence date, historical access dates for individual materials and current external-access status are distinguished. |
| DOI identifier gateway | DOI gateway retained; external material unread | External access not attempted; not acquired | Not read | This gateway was constructed from the retained DOI. It does not represent the original URL field or the format of an acquired physical document. Matsumoto2016 is a report linked in the retained summary. External abstracts, full texts, registration, protocols and analysis plans were not checked in this conversion, and independent clinical validation was not performed. The date is the original check date in retained summary and condition records. The retained verdict’s evidence date, historical access dates for individual materials and current external-access status are distinguished. |
| Article full text | Full text not acquired; unread | External access not attempted; not acquired | Not read | The report’s full text is not acquired or read. Its exact download URL and PDF/HTML format also remain unverified. Matsumoto2016 is a report linked in the retained summary. External abstracts, full texts, registration, protocols and analysis plans were not checked in this conversion, and independent clinical validation was not performed. The date is the original check date in retained summary and condition records. The retained verdict’s evidence date, historical access dates for individual materials and current external-access status are distinguished. |
| Trial registration identifier gateway | Registration identifier gateway; original registration unread | External access not attempted; not acquired | Not read | This gateway was constructed from citation identifier NCT01534910. The original registration field remains unverified, as do the original registration, preregistration and SAP. Matsumoto2016 is a report linked in the retained summary. External abstracts, full texts, registration, protocols and analysis plans were not checked in this conversion, and independent clinical validation was not performed. The date is the original check date in retained summary and condition records. The retained verdict’s evidence date, historical access dates for individual materials and current external-access status are distinguished. |
| Retained verdict summary | Retained verdict summary read | Retained copy acquired; summary read | Stored existing review summary read | The retained Korean/English verdict summary, evidence and citation were read. This does not establish reading of the original abstract, full text or registration. Matsumoto2016 is a report linked in the retained summary. External abstracts, full texts, registration, protocols and analysis plans were not checked in this conversion, and independent clinical validation was not performed. The date is the original check date in retained summary and condition records. The retained verdict’s evidence date, historical access dates for individual materials and current external-access status are distinguished. |

## Review criteria and methods

These are Chamgap's own application conditions, informed by the relevant sections of official methodological guidance. They do not constitute official assessment-tool certification or a new efficacy score.

- M03 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-03) · §3.1, §3.2.1–3.2.3, MECIR C5/C7/C13 · Clearly record the question, eligibility conditions and reasons for changes, and distinguish variations in interventions. · Retained method-application records were reused. External originals were not reread and method content was not reassessed.
- M04 [Cochrane Handbook 6.5.1 (2025), chapter updated 2025-03](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-04) · §4.5, §4.6.1–4.6.3, MECIR C42 · Distinguish studies from reports and link them; do not omit a study solely because results are unreported. · Retained method-application records were reused. External originals were not reread and method content was not reassessed.
- M08 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-08) · §8.1–8.2.3, Table 8.2.a · Define the outcome and effect of interest, then examine randomization, deviations, missing data, measurement and selective reporting. · Retained method-application records were reused. External originals were not reread and method content was not reassessed.
- M15 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-15) · §15.2.4, §15.3.1–15.3.3 · Distinguish effect estimates, intervals, importance and applicability. Sample size alone does not determine precision. · Retained method-application records were reused. External originals were not reread and method content was not reassessed.
- M19 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-19) · §19.1.2, §19.2.1–19.2.4 · Harm questions may require different designs, populations and follow-up from efficacy questions. Case reports do not establish incidence rates. · Retained method-application records were reused. External originals were not reread and method content was not reassessed.

## What the statuses mean

- Met: The retained identity, observation or scope required by this item was checked within stated limits. This does not establish clinical sufficiency or full-text certification.
- Partly verified: Some required facts are known, but the stated conditions involving analyses, populations, formulation or denominators remain unverified.
- Unverified: Direct information is unverified in the retained record. This does not establish an effect of 0, no studies, absence of harm or an unreviewed table.
- Not applicable: An extension obligation outside the narrow question does not apply. This state does not substitute for unread or unverified material.
- Not applicable (alias): This is the gray-display alias of Not applicable.
- Not read: External material was not directly read in this conversion. This is distinguished from reading the retained verdict summary.
- Conflicting data: This covers an actual discrepancy between reports of the same question, denominator and timing. Differences between separate questions are not automatically treated as conflicting data.
