Review decision

To resubmit, address

1. Replace the Key Findings section with distinct, evidence-tied findings: for each outcome class, state what the retained sources show (with at least one effect size or directional statement per source), rather than restating the conclusion.
2. Operationalize 'cardiovascular subgroups' in the Research Question (e.g., subgroups defined by frailty status, sarcopenic obesity, CKM stage, diabetes status, or intervention type) and align the Evidence Landscape categorization with that operationalization.
3. Reconcile the Evidence Landscape table with the limitations narrative: either move the single-source outcome classes into the Limitations section as hypothesis-generating only, or add the missing effect-size columns so the table can be audited against the source bundle.
4. Tighten the Research Question to match the corpus: the 12 sources address frailty, sarcopenic obesity, CKM staging, SGLT2 inhibitors, influenza vaccination, and exercise interventions — the geroscience framing should be downgraded to a cardiovascular risk-stratification or cardiometabolic-subgroup question.
5. Add a short explicit statement that 'direct interventional hard-endpoint evidence' for cardiovascular subgroups in a healthy-aging framework is absent, and that all included sources are either chronic-disease cohorts, post-hoc subgroup analyses, or surrogate-endpoint trials.

Major issues

• The Key Findings section is a near-verbatim duplicate of the Conclusion section, producing redundancy rather than synthesis; the manuscript does not actually present distinct key findings tied to the outcome-class evidence landscape.
• The Evidence Landscape table and per-class summaries provide no actual numeric findings, effect sizes, or directional claims beyond 'positive/negative/null/unclear/mixed' codes, so the synthesis cannot be audited against the cited sources without accessing the supplementary manifest.
• The Research Question conflates a narrow evidence brief on cardiovascular subgroups with a broad 'human geroscience' framing; the question is broader than what the 12-source corpus can answer.

Minor issues

• Several author-year citations (Chen 2026, Wang 2024, Zhang 2025, Kim 2023, Zhao 2025, Lin 2026) are described in the Limitations as anchoring longevity hard-endpoint evidence, but the Evidence Landscape table only codes 2/6 longevity sources as carrying any directional signal and the remaining are indirect or review — the text and table are partially inconsistent.
• The Minami 2025 and Nguyen 2025 sources are not clearly represented in the Evidence Landscape outcome-class allocation; their presence is only implied via the Limitations narrative.
• The phrase 'cardiovascular subgroups' in the research question is ambiguous (subgroups of what?) and is not operationalized in the manuscript.
• The abstract states the corpus is 12 curated references but the Search Summary funnel shows 33 classified source candidates and only 11 strict high-confidence sources; the relationship between these counts is not reconciled.

Reviewer note

This is a rapid evidence synthesis on cardiovascular subgroups in older adults, anchored to 12 traceable sources covering sarcopenic obesity, frailty, CKM syndrome, SGLT2 inhibitors, influenza vaccination, detraining, Baduanjin exercise, and immunomodulatory therapy. The Search Summary is unusually explicit: databases, queries, eligibility criteria, and an admission funnel are all reported, which is a strength relative to typical rapid briefs. The source bundle is internally consistent with the in-text citations, and the Limitations section is genuinely material — it correctly identifies the absence of long-term mortality RCTs, single-source inferences, heterogeneous frailty definitions, narrow endpoint scope, and the mechanism-to-clinic gap. The hedging throughout the Conclusion is appropriate and prevents overclaim at the clinical-recommendation level. However, the manuscript has structural problems that prevent an accept. First, the Key Findings section is essentially a copy of the Conclusion, so there are no distinct evidence-tied findings. Second, the Evidence Landscape table codes directions only as positive/negative/null/unclear/mixed without effect sizes or numeric anchors, making it unauditable against the source bundle without the supplementary manifest. Third, the Research Question is framed at 'human geroscience' scale while the corpus is a narrow 12-source cardiovascular risk-stratification bundle — the question is broader than the evidence. Fourth, there are minor inconsistencies between the Limitations narrative (which treats several primary studies as anchoring longevity evidence) and the Evidence Landscape (which codes most longevity sources as indirect or review). The manuscript is not broken — its sources are real, recent, and directly relevant, its limitations are honest, and its hedging prevents clinical overclaim. But it needs bounded edits: distinct key findings, an operationalized research question, a reconciled evidence table, and tighter scope language. These are achievable with a revision, not a rewrite, so the correct call is revise.
