Original PMC, file link, normalization and regular download checked. Four web calls plus one regular file request; HTML only, no spreadsheet contents. Publisher fallback inaccessible. No new study, repeated notice search or comprehensive recency audit. Inspect AG-D08 original legends and methods for the link between surface-area closure and histological restoration: same animals, times and defined tissue endpoint? Then assess comparability within that model. Park the AG-D09 download route until an original workbook is accessible; do not pool the studies.
Search 17 Oct 2026
Targeted original counterevidence AG-D09 and AG-D08 discussion appraised. Publication and retrieval dates separate; no attributable notice found, non-exhaustive. Direct access partly limited, indexed original passages available; no raw-data or comprehensive recency audit. Inspect original AG-D09 Fig. 2 / Extended Data 7 source data for animal IDs, sex, genotype, time, starting area and two-wound aggregation. With traceable units, calculate direct group differences with uncertainty and a direct sex contrast; otherwise document the specific mapping gap. Do not pool with AG-D08. AG-D09 · 13.11.2024

Title, DOI, date and source access were checked separately. The targeted FTL1/DUB prior-art search did not establish novelty. The June 2026 cardiac study was followed up via PMID 42346394. Press and social sources were not used as outcome evidence. Some PubMed/PMC/Elsevier pages were challenge-protected; source-level access limitations are in the register. Full supplements, all power analyses, conflicts of interest and raw data were not audited. Independent replication was generally not assessed. Clinical intervention studies and trial registers were outside this first mechanistic report; their omission is not an assessment of the clinical field.
Next run: new studies, corrections and independent replications; a focused test of the FTL1/redox/DUB hypothesis. Preserve negative searches and conflicting evidence.
