Why

Review decision

To resubmit, address

1. Replace the 'See the structured evidence table' stubs with one or two short prose paragraphs per outcome class that name the specific sources driving the dominant signal and explicitly note where any two cited sources disagree (direction, population, endpoint).
2. Reconcile the in-text source count (52) with the actual source bundle and either restore missing bundle entries or correct the count; for every named author-year citation in the prose, verify a plausible bundle counterpart exists.
3. For each Findings Map row, attach a one-line source attribution (e.g. 'driven by Edmonston 2024 CRIC; Peng 2025; Liu 2021 meta') so the reader can audit the directional coding against the cited evidence.
4. Disaggregate the 'direct evidence = 0/52' claim: specify that the corpus contains zero direct interventional hard-endpoint RCT evidence for hard clinical outcomes, while human observational direct evidence is in fact present, and recompute the summary statistic accordingly.
5. Expand the Tensions and Gaps section with at least 3–5 concrete tensions (e.g. the U/L-shape dose-response in Nong 2025 vs. the monotonic inverse association in Wang 2025; the positive exercise-induced Klotho signal in Correa 2022/Oliveira 2026 vs. null mechanistic-to-clinic bridging; the paradoxical post-MI mortality signal in R50 vs. the protective inverse association in Edmonston 2024) and tie each to specific sources.
6. Soften or qualify the 'positive signal' coding for single-source slices (Dosing/PK, Frailty, Skeletal/Bone) and add explicit hypothesis-generating caveats in the map, matching the style already used in the Limitations section.
7. Mark external non-corpus references (e.g. Ioannidis 2005) as illustrative rather than bundle sources, or remove them.

Major issues

• The Findings Map section lists each outcome class but then provides only stub paragraphs that defer to the structured table ('See the structured evidence table...') rather than prose synthesis, leaving the map largely a tabular skeleton with no narrative integration of the heterogeneous findings.
• The stated source count of 52 admitted sources is not fully reflected in the source bundle provided (the bundle contains ~46 entries), and several in-text citations (e.g. Mora-Fernandez 2022, Ioannidis 2005, Lopez-Valdes 2025, Rokhsati 2026, Nong 2025, Wang 2026, Ariadel-Cobo 2026) either lack clear bundle counterparts or are bundled but never used in the prose, weakening the audit trail the format promises.
• The 'Contextual Adjacent Evidence' and 'Deficiency Prevalence' rows report 'no extracted directional signal in 5/N' or 'mixed' but the manuscript never explains which specific sources drove these codes or what the signals were, so the heterogeneity is asserted rather than mapped.
• The manuscript asserts 60 non-orthogonal tensions across the corpus and lists 7 narrative gaps, but provides no auditable reconciliation of where those tensions come from, which sources disagree with which, and on what endpoints — a central requirement of an evidence map.
• Several outcomes with single-source slices (Dosing/PK, Frailty, Skeletal/Bone) are presented with directional signals (positive) without any source attribution in prose, so the map cannot be verified against the cited evidence for those classes.

Minor issues

• The Tensions and Gaps section is two sentences and reads as a template placeholder rather than a substantive synthesis of contradictions across the corpus.
• The abstract and scope repeat the same evidence-honesty note verbatim rather than differentiating high-level orientation from inclusion scope.
• Several rows in the Findings Map use the same boilerplate 'limited corpus depth in this outcome class' for both multi-source and single-source slices, obscuring the materially different epistemic status of single-source findings.
• The Tensions and Gaps statement 'direct evidence is 0/52 admitted source(s)' is inconsistent with the inclusion of multiple primary observational studies (e.g. Edmonston 2024 CRIC, Peng 2025, Zou 2025) that are human cohort/clinical — the zero-direct claim conflates 'direct interventional hard-endpoint RCT evidence' with 'direct human evidence'.
• The Limitations section cites Ioannidis 2005 without that source being in the bundle; this is an external reference, not a mapped corpus source, and should be marked as such or removed.

Reviewer note

This is an AI-assisted evidence map of alpha-klotho across 10 outcome classes drawn from roughly 50 corpus sources, with an explicit evidence-honesty note acknowledging the absence of direct interventional hard-endpoint evidence. The scope statement, search summary, and limitations section are reasonably transparent about what the corpus can and cannot support, and the inclusion of a Tensions and Gaps section is appropriate for the article type. However, the manuscript's central deliverable — a faithful, source-attributed map of heterogeneous findings — is largely undelivered in prose. The Findings Map is a structured table whose rows are not tied to specific named sources; the narrative sections under each outcome class are either missing or are one-line stubs that defer to the table. The reported 60 tensions and 7 gaps are not reconciled in text, so the heterogeneity the article type exists to surface is asserted rather than demonstrated. Source-attribution problems compound this: the source count does not match the bundle, several in-text citations (Mora-Fernandez 2022, Ioannidis 2005, Lopez-Valdes 2025) are not in the bundle, and several single-source slice signals are coded 'positive' with no source named in the map. Calibration considerations weigh in favor of revise rather than reject: the bundle is largely plausible, recent, and supports the broad 'Klotho evidence is heterogeneous and biomarker-heavy' thesis; the limitations section is unusually self-aware; and no clinical or policy overclaim is made. The paper is salvageable with bounded edits — fleshing out per-class prose, attaching source names to each map row, reconciling the bundle, and expanding the Tensions and Gaps section — without a scope reset.
