Review decision

To resubmit, address

1. Add a brief note to the Search Summary or Methods clarifying that source bundle verification is limited to reference-level metadata and that exact statistics and effect directions are drawn from the supplementary manifest.json, risk_of_bias.json, and claim registry artifacts.
2. In the Conclusion, explicitly state the population specificity of the strongest longevity signal (selenium-deficient elderly Swedes from the Alehagen trials) as a boundary condition on the claim that CoQ10 'probably reduces' cardiovascular mortality.
3. Resolve the apparent misclassification in the source bundle where several A1-tier direct RCTs (Alehagen 2016, Donnino 2015, Kiani 2024) are labeled 'evidence_type: review' in their bundle excerpts, or document that evidence_type in the bundle reflects pipeline routing rather than study design.

Major issues

• Source bundle is reference-only (title + DOI + excerpt with direction claims, no abstracts or full text). This makes independent verification of the manuscript's reported statistics, effect directions, and claim extractions impossible. While reference-only bundles are valid per calibration rules, the heavy reliance on exact statistics (p-values, CIs, RRs) extracted from sources whose content cannot be audited from the bundle alone creates a verification gap that cannot be resolved without access to supplementary manifests.
• Many source bundle entries describe review-level or indirect directness sources as the primary evidence base. Only 7 of 63 sources are rated as direct clinical evidence. The manuscript acknowledges this but still builds substantial interpretive weight on mortality/longevity signals (Alehagen trials, Xu 2024 meta-analysis) that derive from narrow populations (selenium-deficient elderly Swedes), which limits generalizability more than the conclusion framing suggests.

Minor issues

• Some outcome-class tables repeat identical information across 'Results' and 'Key Findings' sections, adding length without new content.
• The 'Cross-Domain Tensions' table is exhaustive (283 entries) but dense; a summary tier or severity-weighted top-20 list would improve readability.
• A few source bundle entries show discrepancies between the excerpt's evidence_type classification (e.g., 'review' for what appears to be primary RCT data like Alehagen 2016, Donnino 2015, Kiani 2024) and their reported directness tier in the manuscript tables, suggesting possible classification inconsistency in the pipeline.

Reviewer note

This is an unusually rigorous rapid evidence synthesis. The search strategy is fully explicit, the source admission funnel is documented, the evidence is organized by outcome class with directness tiers, and cross-study tensions are systematically mapped rather than averaged away. The manuscript's central thesis — that evidence for CoQ10/ubiquinol is context-dependent and that the anti-aging case remains incomplete — is well-supported by the reported corpus structure. **Strengths:** The PRISMA-ScR protocol, deterministic audit trail, evidence-tension synthesis approach, and the explicit separation of mechanistic plausibility from clinical proof are all exemplary for a rapid synthesis. The limitations section is unusually specific, naming demographic gaps, endpoint asymmetry, and single-source outcome domains. The conclusion correctly bounds the practical implication: promising but insufficient for clinical adoption. **Source grounding concern:** The source bundle contains only reference-level metadata (title, DOI, excerpt with claim direction). No abstracts or full text are included. This means the 63 cited sources cannot be independently verified from the bundle alone. The manuscript reports numerous exact p-values, CIs, and effect sizes that must be drawn from the supplementary manifest artifacts. This is a valid approach per Researka calibration rules, but a brief note in the Methods or Search Summary should clarify this verification architecture for readers who encounter the bundle without the supplementary files. **Mild overclaim on longevity:** The conclusion states CoQ10 has 'selected clinical signals' including in longevity, and the Abstract says the 'anti-aging case is incomplete.' This is well-hedged. However, the strongest longevity signal (Alehagen 2015/2018: HR ~0.51, P = 0.0003) derives from a population with documented selenium deficiency. The manuscript discusses this in the Cross-Domain Synthesis but the Conclusion does not flag this population specificity as sharply as the evidence warrants. Adding one sentence to the Conclusion bounding the longevity signal to selenium-deficient populations would strengthen the already conservative framing. **Synthesis quality:** The outcome-class structure, evidence-tension tables, and cross-domain synthesis represent a genuinely integrated argument rather than a loose summary. The 283-tension table, while dense, demonstrates systematic disagreement mapping. The Endpoint-Sensitivity Framework and Boundary-Condition Matrix add interpretive structure that many rapid syntheses lack. **Overall verdict:** This manuscript is strong enough to be salvageable with bounded edits. The two required revisions (verification architecture note, longevity signal population specificity) and one source bundle classification fix would bring it to accept quality. The evidence is genuinely mixed and the manuscript says so — this is exactly the condition where revise is the correct call, not accept.
