To resubmit, address

1. Reconcile the source-level directional coding with the actual reported findings in the bundle excerpts; if 4–5 sources clearly report significant associations (Sheng, Luo, Azizzadeh, Lu, Alanis), the 'null receipt-level direction' coding is inaccurate and must be corrected or explained.
2. Add a substantive Key Findings section that integrates specific reported findings from at least the direct evidence sources (Sheng 2025 ePWV-CAD HR; Lu 2026 NCAA-HR; Wang 2024 Tai Chi RCT; Luo 2025 meta-analysis effect sizes) rather than restating outcome-class headers.
3. Provide actual within-class synthesis narrative for each outcome class describing what the cited studies found, not just metadata counts.
4. Fix the Research Question to state a concrete, answerable question rather than 'what does the corpus establish.'
5. Clarify the contradiction between the abstract's claim of 11/13 null-coded sources and the bundle excerpts showing multiple sources with significant reported statistics.
6. Resolve or remove the duplicate/malformed rows in the Evidence Landscape table.

Major issues

• Evidence Landscape and Key Findings sections are largely repetitive metadata tables with no narrative integration of the 13 sources — the manuscript reads as a receipt of bundle state rather than a synthesis.
• The Research Question is stated twice identically with only the evidence-honesty notes attached; no actual question framing is present beyond 'what does the corpus establish.'
• The Conclusion repeatedly asserts tiered, non-supportive interpretation but provides no substantive synthesis of what the cited sources actually report — it reads as a disclaimer rather than a bounded answer.
• Despite the manuscript acknowledging 11/13 sources are null/non-directional, it admits sources ranging from cross-sectional protocols to RCTs to mechanistic reviews without resolving what each actually contributes to the vascular-age thesis.

Minor issues

• Many sections (Key Findings, Evidence Landscape sub-sections) repeat the same outcome-class note verbatim without adding new content.
• The Methods/Search Summary is detailed but the Synthesis Approach paragraph describes evidence-tension synthesis that is not visible in the Results — no within-class agreement/disagreement is actually surfaced.
• Source bundle excerpts contradict the manuscript's coding: Sheng 2025 reports a significant HR for ePWV and CAD (HR 1.50, p<0.001); Luo 2025 reports significant FMD improvement from L-citrulline; Azizzadeh 2026 reports clear EVA prevalence and determinants; Lu 2026 reports significant NCAA-CVD association — yet all are coded as 'null' direction, suggesting the directional coding may systematically undercount actual reported findings.
• Gaps section references '12 disagreement(s)' without identifying what they are.
• The Evidence Landscape table is malformed — duplicate 'no dominant outcome class' entries and missing row content for several outcome classes.

Reviewer note

This manuscript is a rapid evidence synthesis on 'vascular age' that draws on 13 sources spanning primary research, reviews, protocols, and mechanistic studies. The search scope and protocol reporting are detailed and auditable, which is a strength. However, the core synthesis is weak: the Evidence Landscape and Key Findings sections consist almost entirely of repetitive metadata tables with no narrative integration of what the cited studies actually report. The Conclusion is a long disclaimer about non-supportiveness rather than a bounded answer to a question. A significant internal inconsistency undermines the manuscript: the bundle excerpts show multiple sources reporting significant findings (Sheng 2025 ePWV HR 1.50, p<0.001 for CAD; Lu 2026 NCAA HR 1.21 for CVD; Luo 2025 significant FMD improvement; Azizzadeh 2026 clear EVA prevalence data), yet all are coded as 'null receipt-level direction.' This may reflect a conservative coding rule, but it contradicts the evidence-honesty framing and obscures what the corpus actually says. The manuscript is honest about its limitations (1 direct source, 12 indirect, endpoint heterogeneity) and appropriately avoids causal/policy escalation. But 'honest about weakness' is not the same as 'well-synthesized.' The paper needs bounded edits to: (1) reconcile directional coding with reported findings, (2) add actual synthesis narrative integrating specific results, (3) fix the malformed tables and duplicated sections, and (4) state a concrete research question. Recommendation: revise.
