Why

Review decision

To resubmit, address

1. Add a narrative synthesis section that explicitly maps findings to the five subgroup lenses (frailty, sarcopenic obesity, CKM stage, diabetes comorbidity, intervention type) using the admitted sources, rather than only listing source counts.
2. Expand the underpopulated outcome-class subsections (Longevity, Muscle Function, Immune Inflammation, Safety, Safety and Comorbidity) with at least one or two attributed findings each, drawn from the source bundle, or remove the headers if no findings are retained.
3. Strengthen the Tensions and Gaps section by naming specific disagreements among the retained sources (e.g., sarcopenic obesity and CVD risk in Zhang 2025 vs. anthropometric paradox in Yang 2025/Erdogan 2025; frailty subgroup benefit in Nguyen 2025 vs. Rubino 2026) and identifying the specific evidentiary gaps those disagreements reveal.
4. Reconcile the source count between abstract (63) and the Findings Map rows, and clarify how the admission funnel categories map to the final admitted set.
5. Where the extraction returned 'unclear signal' for most sources in an outcome class, state explicitly that the corpus did not yield directional findings for that class rather than presenting empty structured-table rows as if they constituted mapping.

Major issues

• The Findings Map section is essentially a tabular summary of source counts by outcome class with directional coding, but it lacks any integrated narrative interpretation across outcome classes, subgroups, or evidence tiers — it reads as a structured list rather than a synthesized landscape.
• Several outcome-class subsections (Longevity, Muscle Function, Immune Inflammation, Safety, Safety and Comorbidity) consist only of one- or two-sentence pointers to the structured table, with no actual findings articulated. The heterogeneity the article is supposed to map is not surfaced in prose.
• The manuscript claims to map findings across cardiovascular subgroups (frailty, sarcopenia, CKM, diabetes, intervention type) but the Findings Map does not consistently attribute specific findings to specific subgroup lenses; the link between source content and the subgroup operationalization stated in the abstract is weakly developed.
• Tensions and Gaps section is generic and prescriptive (run more adequately powered studies, standardize exposure), without naming the specific tensions or contradictions among the mapped findings — for example, the disagreement between Zhang 2025 (sarcopenic obesity OR 1.95 for CVD) and Liu 2025b (plant-based diet effects in sarcopenia) is not surfaced.
• The evidence-honesty framing correctly avoids overclaiming, but the 'strongest signal' column for almost every outcome class is 'unclear signal' or 'no extracted directional signal,' which limits the map's value as a landscape and suggests the extraction did not produce interpretable directionality for most domains.

Minor issues

• Source bundle cites 63 sources in the abstract but the Findings Map shows ~64 rows across categories — minor inconsistency in source counting.
• The Search Summary admission funnel lists 'Mixed partial-or-none' (70) and 'Partial-only' (7) candidates that are not clearly explained in the manuscript prose.
• Outcome-class labels are repeated inconsistently (e.g., 'Immune Outcomes' and 'Immune Inflammation Outcomes' appear as separate headers).
• Several sources in the bundle (e.g., Rubino 2026 SENIOR-RITA, Nguyen 2025 CANVAS/CREDENCE, Wolfe 2025 ASPREE, Sheikh 2025 HELIOS-B) are highly relevant to the cardiovascular-subgroups-in-older-adults thesis but are not explicitly invoked in the Findings Map narrative.

Reviewer note

This evidence-map submission correctly identifies itself as a hypothesis-generating brief, appropriately flags that 57/63 sources are indirect/review-level, and bounds its interpretation to avoid causal or policy claims. The search summary is auditable, the source bundle is recent and directly relevant to cardiovascular subgroups in older adults, and the cited sources genuinely exist and match the topic (e.g., ASPREE extended follow-up, HELIOS-B age subgroup analysis, SGLT2 inhibitor meta-analyses in older adults, sarcopenic obesity meta-analysis, CANVAS/CREDENCE frailty subgroup analysis). Source grounding is therefore solid. However, the synthesis itself is weak. The Findings Map is essentially a structured table of source counts and directional coding with no integrated narrative. Several outcome-class subsections contain no actual findings — only pointers to the table. The promised subgroup lens (frailty, sarcopenia, CKM, diabetes, intervention type) is articulated in the abstract but not systematically applied in the map. The Tensions and Gaps section is generic rather than surfacing specific disagreements visible in the source bundle (e.g., the sarcopenic obesity/anthropometric paradox tension, the divergent frail-vs-nonfrail subgroup results across SGLT2 and NSTEMI trials, the conflicting influenza vaccine subgroup findings in Nielsen 2026 vs. Skaarup 2026). Because the source bundle is strong and the framing is honest, the manuscript is salvageable with bounded edits: expand narrative mapping per subgroup, populate the empty outcome-class subsections with attributed findings, and convert generic gaps into specific tensions. A revise recommendation is appropriate — the evidence map is not broken, but it has not yet earned acceptance because the synthesis dimension is materially underpopulated.
