1. Rebuild the synthesis around what the actual corpus addresses. The retained 17 sources cover myopia in children, wound healing, post-stroke cognition, obesity metabolism, female fertility, erectile dysfunction in mice, keratinocyte scratch assays, endothelial function reviews, dysmenorrhea, cytochrome c oxidase kinetics, and skeletal muscle myoblasts in vitro. Either narrow the research question to match this corpus (e.g., 'What does the retained corpus establish about red-light photobiomodulation across heterogeneous clinical and preclinical contexts?') or expand retrieval to include direct geroscience/anti-aging human trials.
2. Populate the Key Findings section with actual narrative findings per outcome class, integrating the source-level statistics and directions that are currently buried in the Evidence Landscape tables.
3. Reconcile the effect_direction coding in the source bundle with the abstracts. Where an abstract clearly reports positive or null effects (e.g., Nardi 2025 +9.3% REE p<0.001; Anita 2025 ICP restored to 90%; Couturaud 2023 skin aging reversal), code the direction accordingly rather than 'unclear'.
4. Expand the Gaps section to cover all five outcome classes (immune/inflammation, contextual adjacent, mechanism, muscle function, safety/comorbidity), not just two.
5. Either include the uncited sources (Colombo 2021, Couturaud 2023, Phypers 2024, Mathioudaki 2023, Yang 2025, Soliman 2024, Pelevin 2026, Quirk 2021) in the Evidence Landscape prose or explain why they were admitted to the bundle but not synthesized.
6. Clarify the claim-counting methodology: explain how 433 high-confidence claims map to 17 sources, and what 'high-confidence' means in the extraction protocol.
7. Remove or temper the 'geroscience case' and 'anti-aging' framing that the corpus does not support, or restrict it to the single geroscience-relevant source (Huang 2025, which is actually about post-stroke cognition, not aging per se).

Major issues

• The abstract and Research Question both state '17 accepted source papers and 433 high-confidence extracted claims' but the Evidence Landscape table and source bundle enumerate 17 sources with only 1 direct clinical source for PBM anti-aging. The framing as a 'geroscience case' and 'anti-aging' topic is not directly addressed by the source bundle: the only direct clinical source (Huang 2025) addresses post-stroke cognitive impairment, and the other sources cover myopia, wound healing, obesity metabolism, fertility, erectile dysfunction in mice, keratinocytes, etc. The corpus is largely off-topic for the stated anti-aging/geroprotection question.
• Several source bundles cited in the Evidence Landscape (e.g., Anita 2025, Fan 2025, Nardi 2025, Merkle 2026, Huang 2025, Parigi 2025, Obajuluwa 2025, Deng 2024) match the bundle, but the Evidence Landscape does not cite several sources present in the bundle (Colombo 2021, Couturaud 2023, Phypers 2024, Mathioudaki 2023, Yang 2025, Soliman 2024, Pelevin 2026, Quirk 2021, Li 2025). The Key Findings section is essentially empty, providing no narrative synthesis beyond a repeated header note.
• The Gaps section lists 'immune inflammation, contextual other' as the only outcome classes needing study, omitting muscle function, mechanism, and safety/comorbidity entirely, despite these being separate slices in the Evidence Landscape.
• The receipt-level direction is coded 'unclear' for almost all sources even where abstracts report positive or null effects (e.g., Nardi 2025 reports +9.3% REE with p<0.001; Anita 2025 is coded positive; Soliman 2024 is coded null but reports >50% faster healing per blinded evaluators). This conservative coding protects against overclaim but means the synthesis cannot effectively distinguish positive, null, and negative signals as the abstract claims.

Minor issues

• Key Findings section contains only a repeated header note and the outcome-class caveat, providing no actual narrative findings.
• The Source-context map separates 'Aging and geroscience' (1 source, no signal) from 'Skeletal and muscle' but the underlying source mapping is not shown — readers cannot verify which source falls into which context.
• The Search Summary describes a frozen deterministic protocol but does not explain why the chosen sources diverge so sharply from the stated anti-aging/geroprotection research question.
• Many effect_direction fields in the source bundle are coded 'unclear' even when abstracts clearly state direction, undermining the usefulness of the synthesis.
• The phrase '433 high-confidence extracted claims' is repeated verbatim in abstract, Research Question, and Gaps without explanation of how claim counts map to the 17 sources.

Reviewer note

This rapid evidence synthesis presents a tiered, conservatively-coded profile of 17 sources on photobiomodulation/red light therapy. The search summary is unusually explicit, the limitations are honest about evidence-role imbalance and endpoint heterogeneity, and the conclusion appropriately avoids clinical recommendation. However, there is a substantial mismatch between the stated research question (photobiomodulation as a geroscience/anti-aging intervention) and the actual source bundle, which is dominated by off-topic studies (myopia in children, wound healing, fertility, obesity metabolism, keratinocyte scratch assays, dysmenorrhea, cytochrome c oxidase kinetics). The only directly clinical source (Huang 2025) addresses post-stroke cognitive impairment, not aging. The Key Findings section is empty beyond repeated header notes, leaving the Evidence Landscape tables as the entire narrative substance. Effect directions are coded 'unclear' for most sources even where abstracts clearly report direction, undermining the synthesis's ability to distinguish positive from null signals as claimed in the abstract. Source_grounding is partial: several sources in the bundle are not cited in the Evidence Landscape prose, and the geroscience framing is not directly supported by the cited corpus. The manuscript is structurally credible and the tiered/hedged conclusion is appropriate, but the research question needs to be narrowed to match the actual corpus, the Key Findings section needs to be populated, and effect directions need to be reconciled with the abstracts. These are bounded but non-trivial fixes, so the recommendation is revise.
