Review decision

To resubmit, address

1. Reconcile the Opstad 2022 framing: explicitly state whether the 'positive' coding refers to the within-trial LTL change contrast (p = 0.02) or the secondary cardiovascular mortality finding, and align the Results, Cross-Domain Synthesis, and Evidence Snapshot rows accordingly.
2. In each outcome-class Results subsection, anchor at least one concrete numeric (effect size, CI, p-value) to the specific source bundle entry, so direction claims are traceable rather than asserted at the slice level.
3. Harmonize outcome-class terminology: choose 'contextual adjacent evidence' or 'contextual_other' and apply uniformly across tables and prose.
4. Clarify Su 2025's role: it is a review-level meta-analysis of RCTs (per the bundle excerpt). The Evidence Landscape table currently lists directness=review and evidence_type=review, which is correct; ensure the Results prose describing it as 'Su 2025 functions as a clinical RCT meta-analysis' does not conflate it with a primary RCT.
5. Tighten the title and abstract opening to reflect the scoping, tiered nature of the synthesis; remove framing that could be read as a definitive verdict on telomere-rate interventions.
6. Add a short paragraph in Limitations explicitly addressing whether the direction coding decisions (positive vs null vs unclear) were anchored to pre-specified source-level statistics versus author interpretation, and disclose any coding disagreements.

Major issues

• The title 'Telomere Rates — full paper' does not reflect the manuscript's bounded framing; it reads as a definitive evidence review rather than a tiered scoping synthesis, and the research question is presented more clearly inside the manuscript than in the title/abstract surface.
• The Evidence Landscape table lists 'Pitt–mental-training telomere response' attributed to Puhlmann 2019 in Limitations but the cross-domain synthesis does not consistently integrate this single-study signal; coverage of single-source fragility is uneven across outcome classes.
• Several outcome-class sections (e.g., contextual adjacent evidence, immune and inflammation) lack explicit numeric summaries tied to specific studies; the prose leans on 'mixed'/'heterogeneous' framing rather than enumerating study-level effect sizes present in the bundle, reducing traceability of direction claims.
• The Opstad 2022 row is tagged 'positive' but the bundle excerpt reports 'Subjects suffering future death presented with significantly shorter LTL at 42 months than survivors' alongside an active-treatment effect on LTL change (p = 0.02; p < 0.001 for individual changes); the manuscript's narrative oscillates between framing Opstad as positive and as conditional on mortality endpoint without reconciling these.
• The 'Su 2025' source is labeled a 'review' but the bundle excerpt explicitly states 'PRISMA-guided meta-analysis evaluated 8 randomized controlled trials (RCTs)' — this is review-level synthesis of RCTs; the manuscript sometimes refers to it as a primary RCT meta-analysis inconsistently with directness coding.
• The source bundle and manuscript are described as reference-only at points, yet numerous exact statistics (HR, OR, SMD, β with CIs, p-values) are repeated verbatim from bundle excerpts; reviewer must verify these match the cited DOIs. Spot checks (e.g., Sasmita 2025 'pooled HR 1.97', Xiao 2025 'HR 0.402', Ryall 2025 'SMD 0.36', Sun 2026 'SMD -0.03', Sun 2025 'SMD 0.59') appear to match but full audit is not visible.

Minor issues

• The Abstract is duplicated almost verbatim between the dedicated Abstract section and the start of the main text, which is acceptable for scoping reviews but could be tightened.
• Outcome-class labels mix 'contextual adjacent evidence' and 'contextual_other' between tables and prose; harmonize terminology.
• 'Telomere rates' as a phrasing is grammatically odd — 'telomere attrition rates' or 'telomere length change rates' would be clearer; the manuscript itself uses 'telomere rate' inconsistently.
• Load-Bearing Tensions list contains seven entries that all flag the same Wojcicki 2023 vs A1 direct sources; this could be consolidated.
• The Metabolic-Functional Tradeoff Framework section introduces a paper-level organizing claim that adds interpretive structure but no source-level evidence; acceptable but should be flagged as such in the limitations.
• Several long parenthetical citations inside Results prose (e.g., the Liu 2025a frailty subsection) repeat the bundle reference multiple times within one paragraph.

Reviewer note

This is a gatekeeper-tier scoping synthesis of 56 sources on telomere-length dynamics across nine outcome classes. It demonstrates several strengths expected of the article type: explicit PRISMA-ScR framing, deterministic admission funnel, tier/directness coding with reproducibility claims, an Evidence Landscape table that surfaces every admitted row, a Cross-Domain Synthesis section that integrates mechanism/clinical/dose/comparator boundaries, a Boundary-Condition Matrix and Evidence-Gap Priority list, and a Limitations section that names specific methodological constraints (single-source slices, surrogate-endpoint caveats, external-validity gaps). The Conclusions are appropriately bounded and the abstract carries the research question framing. Source grounding is solid: 56 cited_as entries map cleanly to bundle rows with matching DOIs and titles; the cited excerpts support the headline numerics (e.g., Opstad 2022 p < 0.001 for LTL change; Ojeda-Rodriguez 2024 null; Sasmita 2025 pooled HR 1.97 for recurrence; Xiao 2025 HR 0.402 for all-cause mortality; Sun 2025 SMD 0.59 for TL maintenance; Sun 2026 SMD -0.03 null for periodontitis–TL; Ryall 2025 SMD 0.36 for VO2max–TL). Recent literature is well represented (multiple 2024–2026 primary RCTs and reviews). Weaknesses that prevent an accept: (1) outcome-class direction codes are derived from the bundle's effect_direction field and propagated into prose, but the Results sections for contextual adjacent evidence and immune/inflammation do not anchor those directions to specific study numerics, weakening traceability; (2) the Opstad 2022 'positive' coding is left ambiguous between within-trial LTL change and the cardiovascular-mortality secondary endpoint; (3) Su 2025 is variously described as 'review' and 'clinical RCT meta-analysis' — the latter is fine if clarified, but inconsistency between Evidence Landscape and prose is a minor but real source-typing inconsistency; (4) terminology drift between 'contextual adjacent evidence' and 'contextual_other' across tables and prose; (5) the title is generic for a synthesis that explicitly disclaims broad causal/clinical claims. None of these is fatal, but together they require bounded edits before the manuscript reaches accept tier. Recommendation: revise.
