Review decision

To resubmit, address

1. Reconcile the source bundle to the 15 admitted sources: either add the missing source-level finding for Chakraborty 2026 and/or Chan 2012 in the Findings Map, or explicitly exclude them from the admitted set with reason, so internal accounting matches prose.
2. Re-code and reconcile effect directions against bundle excerpts: Hsiao 2026 reports significantly higher mtDNA damage in BPD infants (not null), Ng 2019's null lifespan finding should be flagged as a tension with mechanistic plausibility, and Pena 2024's p=0.92 representative statistic should be presented as a non-significant contrast rather than as evidence of a 'positive' direction.
3. Redo the Tensions and Gaps section to honestly enumerate the contradictions the corpus does contain (positive reversal vs. negative damage induction vs. null lifespan effect), instead of reporting '0 disagreements.'
4. Reclassify human cohort/biopsy sources (Roca-Bayerri 2020, Reid 2023, Picca 2019/2020) as adjacent human evidence rather than treating the entire corpus as indirect/mechanistic; update the '0/15 direct' framing accordingly.
5. Provide an auditable admission funnel: either present non-overlapping buckets or show the dedup/eligibility step-by-step so candidate union → admitted sources is verifiable.

Major issues

• Manuscript text claims only 15 retained sources but source bundle contains 16 entries (Chan 2012 is present in the bundle but absent from the body text's source-level findings and admission accounting); this is an internal consistency defect in the cited corpus.
• Several cited findings are miscoded relative to the bundle excerpts. Pena 2024 is a G2019S LRRK2 inhibitor paper that reports reversal of mtDNA damage in models/patient cells; the manuscript cites it as 'representative non-significant statistic p = 0.92' and effect_direction='positive' in the Findings Map while the bundle lists effect_direction='unclear'; the LRRK2-inhibitor-abrogates-mtDNA-damage finding is presented as a positive directional signal that is then undermined by 'non-significant' framing. Shimizu 2026 is described as 'negative signal' and 'PUFA-rich diet increases... mtDNA damage in mice'; the bundle confirms a negative direction in the PUFA arm, but the broader claim that cardiometabolic mtDNA damage has a negative direction profile across the corpus is not supported by a single mouse mechanistic study and is over-extrapolated.
• The Tensions and Gaps section says '0 disagreement(s)' were surfaced, yet the corpus contains genuinely contradictory signals (e.g., Ng 2019 finds mtDNA damage does not determine C. elegans lifespan vs. mechanistic plausibility claims; Shimizu 2026 negative signal vs. Pena 2024 and Chakraborty 2026 positive reversal signals; Hsiao 2026 null coding vs. the abstract reporting significantly higher mtDNA damage in BPD). Smoothing these to zero disagreement misrepresents the landscape.
• The manuscript repeatedly asserts 'no direct interventional hard-endpoint evidence' and '0/15 admitted source(s)' direct, yet Roca-Bayerri 2020, Reid 2023, and Picca 2019/2020 contain human cohort/biopsy data with clinical correlates (HIV NCI, AD risk, SPPB); classifying all 15 as indirect/mechanistic over-restricts the evidence base and contradicts the bundle's evidence_context field (some are coded 'adjacent', not 'context').
• Admission funnel arithmetic is internally inconsistent: 'classified source candidates = 18' but only 15 admitted; subsequent audit buckets (no extractable claims=9, none-only=3, mixed partial-or-none=14, partial-only=2, strict=1) overlap and sum to >18, and the manuscript acknowledges this yet provides no auditable reconciliation. This makes the landscape boundary non-auditable.

Minor issues

• The next-study design recommendation gives concrete numbers (n≥200/arm, ≥12 months) but is not tied to any specific outcome domain's gap; it is generic guidance dressed as actionable.
• The 'no load-bearing cross-source disagreements' claim in Evidence Landscape is contradicted by the Findings Map's own mixing of negative, null, and unclear directions across outcomes.
• Year 2026 appears in multiple bundle entries (Hsiao 2026, Shimizu 2026, Chakraborty 2026, Perez-Perez 2025 listed as 2025); given knowledge cutoff, future-dated sources should be flagged or verified, not silently cited as if established.
• Chakraborty 2026 appears in the source bundle but is never summarized in the Findings Map's outcome-class sections; it is silently dropped from the mapped findings despite being counted in the 15-source total.
• 'Receipt-level direction coded unclear' is used so frequently that it effectively renders the direction-profile table uninformative; unclear coding should be distinguished from null coding more transparently.

Reviewer note

This evidence map attempts a faithful, source-attributed landscape of mitochondrial DNA damage across 15 sources spanning multiple outcome classes, with explicit attention to directness, evidence tier, and direction coding — the correct posture for an evidence-map review. However, several defects prevent acceptance: (1) the admitted-source count (15) does not match the source bundle (16 entries), with Chakraborty 2026 silently dropped from prose; (2) the corpus genuinely contains contradictory signals (Ng 2019 null on lifespan, Shimizu 2026 negative, Pena 2024 positive reversal, Hsiao 2026 reported as positive in abstract but coded null), yet Tensions and Gaps reports '0 disagreements'; (3) the 'no direct evidence / 0/15' framing over-restricts the corpus because several bundle entries are human adjacent studies coded 'adjacent' rather than 'context'; (4) the admission-funnel arithmetic is non-auditable despite being presented. The scope is bounded, findings are source-attributed at the row level, and heterogeneity is structurally represented via outcome-class separation — strengths. But the smoothing of real tensions, the source-count mismatch, and the funnel opacity mean the map is not yet a faithful landscape. Bounded revisions — reconcile bundle to prose, recode directions against excerpts, surface actual contradictions, reclassify human-adjacent evidence, and fix funnel arithmetic — would bring this to accept quality.
