Why

Review decision

To resubmit, address

1. Clarify the disconnect between the evidence landscape showing null directional signals across all outcome classes and the conclusion's suggestion that the corpus supports proteomic age clocks as a general health intervention. Either the directional coding is incomplete or the conclusion overclaims.
2. Fix the truncated sentence in the abstract.
3. Explicitly state in the conclusion that all 15 sources are indirect and observational, and that the 'bounded geroscience rationale' is purely associational with no direct human interventional support.

Major issues

• The Evidence Landscape table reports 'no extracted directional signal' for every outcome class, yet the manuscript asserts a 'bounded geroscience rationale' and that 'the current corpus may support plasma proteomic age clocks as a general health or lifestyle intervention.' This tension between uniformly null directional coding and affirmative language is unresolved and not adequately explained.

Minor issues

• The abstract ends with an incomplete sentence ('is consistent with') suggesting a drafting artifact.
• Gaps section states 'direct evidence is 0/15 admitted source(s),' which if accurate severely undermines the claim that any clinical utility is supported, yet the conclusion still frames the topic as 'worth structured follow-up.'

Reviewer note

## Review ### Strengths The research question is specific and clearly stated. The search summary is unusually thorough for a rapid synthesis, with explicit queries, information sources, a source admission funnel, and an AI-use disclosure. The limitations section is exemplary: it names specific population gaps, the absence of RCTs, single-source outcome domains, and endpoint scope limitations with material precision. The gaps section identifies actionable next steps (run adequately powered human studies, standardize endpoints, separate direct from adjacent evidence). ### Concerns **Directional coding vs. conclusion language:** The Evidence Landscape table reports 'no extracted directional signal' as the strongest signal for every single outcome class (cardiometabolic, longevity, immune, safety, contextual). All 15 sources are coded as indirect. Yet the Conclusion states 'the current corpus may support plasma proteomic age clocks as a general health or lifestyle intervention where otherwise indicated.' This is a material tension that the manuscript does not resolve. If the directional coding is accurate, the conclusion should not suggest even conditional support. If the directional coding is incomplete (e.g., Argentieri 2024's abstract clearly describes positive associations with 18 diseases and all-cause mortality), then the evidence landscape table is misleading and needs correction. **Source grounding:** The source bundle is reference-only (titles, DOIs, excerpts). Several sources clearly discuss proteomic aging (Argentieri 2024, Wang 2025, Oh 2025, Kuo 2024, Ma 2025), while others appear tangential (Navarro 2015 is a glucosamine RCT, Lee 2016 is about Nepalese children and cognition, Gonzales 2020 is about HIV-infected malnourished children). The manuscript acknowledges some of this heterogeneity in Limitations but the source admission process does not explain why these tangential sources were included as core evidence. The score of 3 reflects partial support: some sources directly address proteomic age clocks, others do not. **Drafting artifact:** The abstract ends mid-sentence ('remains to be is consistent with'), which is a fixable error but suggests incomplete review before submission. ### Verdict The manuscript is structurally sound, with excellent search reporting and limitations. However, the core tension between uniformly null directional coding and affirmative conclusion language is a material issue that requires either correction of the evidence landscape or revision of the conclusion. This is fixable with bounded edits, so the recommendation is **revise** rather than reject.
