Fairness in histopathology AI — systematic review: extraction, audit, and verification artifacts (79-study corpus, manuscript v0.3.6)

Machine-readable evidence and analysis code for a PRISMA-2020 systematic review of fairness in histopathology AI. Contents. (i) The dual-coded, adjudicated extraction table for the 79-study analytical corpus (62 from the main search plus 17 from the demographic-term update; the 62-study tables are kept alongside), with the raw multi-coder outputs and inter-coder agreement statistics; (ii) the screening, de-duplication and post-hoc eligibility-audit logs; (iii) adjudicated QUADAS-2 risk-of-bias judgements for all 79 studies, with per-coder judgements for the original 62; (iv) the full consensus-endorsement coding pipeline — screened review pools, the pre-specified random sample (n=30, seed 20260913), the coding specification, two independent coder passes, disagreements and their adjudication, and tallies with Wilson 95% confidence intervals; (v) the 39-dataset demographic-metadata audit; and (vi) a claim-by-claim statistics register mapping every reported number to its source rows, together with the code that produces each value.

A SHA-256 manifest (MANIFEST.sha256) covers every file in the package. This package is a working-tree snapshot of the manuscript as of 1 October 2026 (46 pp main + 28 pp supplementary). Manuscript v0.3.6 (1 October 2026). Paragraph-level Jev quality check of the abstract and five chapters, read by hand. Four passages were reworded so that causal or directive phrasing matches a descriptive review: the Discussion priorities paragraph, the Discussion "Second... Third" paragraph, the Discussion policy paragraph, and the opening sentence of the Results algorithmic-bias paragraph. No number, citation or coded value changed. Headlines remain 67/79 any bias category, 25/79 (31.6%) any fairness metric, 41/79 (51.9%) external validation, and overall risk of bias 6 low, 54 unclear, 19 high. The manuscript is 46 pages and the supplementary materials are 28 pages. Full texts of the reviewed papers are not included.
