Review decision

To resubmit, address

1. Verify and correct the content-to-source mapping for each row; in particular, fix the prescription-rate row (10.1136/bmjdrc-2023-003666) and the mechanistic ejhf.1732 row so that the finding actually matches the cited source's topic and result.
2. Separate pre-clinical/animal/mechanistic findings from human clinical or observational findings (e.g., add a 'Study type' column or sub-group rows) so heterogeneity across evidence tiers is explicit rather than silently flattened.
3. Add concrete search-summary detail: date range, databases, and at least a one-sentence inclusion criterion (e.g., 'direct A_core findings on SGLT2 inhibitors in the Tier-2 corpus'), so the scope is auditable.
4. Expand the Tensions and Gaps section to name at least 2–3 specific tensions or single-source gaps (e.g., male-only mouse lifespan extension, FAERS pancreatitis signal, comparator heterogeneity) rather than restating the heterogeneity caveat generically.

Major issues

• Mismatched source attributions: the row citing '10.1136/bmjdrc-2023-003666' for a 114.6% prescription-rate increase does not match the bundle entry whose actual topic is euglycemic diabetic ketoacidosis — this is a substantive content/citation mismatch.
• The row citing '10.3389/fcvm.2021.747620' for Alzheimer's incidence (0.01 vs 0.1%) is attributed to a DPP4-vs-SGLT2 dementia study; the effect direction and specific percentages cannot be verified as drawn from that source without the full text, and the framing ('SGLT2I users had lower incidences of Alzheimer's') risks overclaim given the comparator is DPP4i, not placebo.
• Several rows appear to truncate or mis-summarize their cited sources (e.g., the 2020 ejhf.1732 row claims a 25–40% HF risk reduction from a source titled 'Autophagy Stimulation and Intracellular Sodium Reduction…' which is a mechanistic/review piece, not the >40,000-patient five-trial synthesis implied); this makes the source-to-finding linkage unreliable for at least 2–3 rows.
• Some findings are from non-clinical or pre-clinical models (UM-HET3 mice, C57BL/6J mice, db/db mice) but are listed alongside human RCT/observational findings without any clear separation, weakening the map's ability to honestly convey heterogeneity between mechanistic, animal, and human evidence.

Minor issues

• Search Summary does not specify search terms, date range, or inclusion/exclusion criteria — only that 24 sources were 'retrieved from the Tier-2 semantic corpus,' so the landscape's boundaries are not fully auditable.
• Comparator column is populated as '—' for many rows even when the underlying study has a defined comparator, which reduces the structural value of the population/comparator/endpoint/effect schema.
• Tensions and Gaps section is generic and does not name any specific tensions (e.g., the male-only lifespan extension in mice vs. human cardiovascular benefit, or the pancreatitis FAERS signal vs. cardiovascular benefit) that the map could surface.

Reviewer note

The submission is a competent evidence map of 24 SGLT2-inhibitor sources with the right structural intent: a findings table keyed to population, comparator, endpoint, and effect, an explicit refusal to pool across rows, and a stated scope question. The biggest problem is content-to-source fidelity: at least two rows (the prescription-rate row mapped to the euglycemic DKA paper, and the 25–40% HF risk reduction attributed to a mechanistic autophagy review) do not match their cited sources, which is a substantive defect in a source-attributed map. A second issue is the silent mixing of animal/mechanistic rows with human clinical/observational rows in the same table without differentiation, which undercuts honest representation of evidence heterogeneity. With the source mismatches corrected, the study-type separation added, the search summary made auditable, and the Tensions and Gaps section made specific, this would be a strong evidence map. In its current form it is salvageable with bounded edits but not yet acceptable.
