POTS findings v1.2, package 3 of 5: EDS and hypermobility, ME/CFS, MCAS, fibromyalgia, IBS, small fiber neuropathy and RCCX genes, part 2 of 2 (33,830 findings, 2,589 papers)

Package 3 of 5. 33,830 structured findings extracted from 2,589 papers (2020–2026) covering EDS/hypermobility, ME/CFS, MCAS, RCCX genes, fibromyalgia, IBS, small-fiber neuropathy, patient-generated evidence, gastroparesis. Findings were extracted by a language model (Anthropic claude-sonnet-5) from PubMed and Europe PMC records and full texts. The full method (docs/METHODS.md in each package), the build code and a searchable browser are listed under Related works. One block of a five-way partition of an 11,519-paper, 148,186-finding corpus of the POTS, dysautonomia and comorbid-condition literature. The five packages share no PubMed record; per-package counts sum exactly to the corpus totals. 14 studies appear as a preprint in one package and as the published version in another; annotations/paper_flags.csv links them. Self-contained. Includes the findings table (parquet and CSV), a data dictionary with fill rates measured on this slice, the QA evidence behind every stated number, the pinned extraction and validation code, and code/verify_package.py, which re-derives every headline number from the shipped data and exits non-zero on disagreement. Ontology identifiers (v1.2): every identifier the extraction model emitted was checked by id at its authority (HGNC, ChEBI, MeSH). Of 5,573 rows with an id, 3,880 were confirmed, 908 were replaced by the id the entity name resolves to, and 785 were withheld. Join only on rows where ontology_id_verification is authority_verified or authority_verified_retrospective. See LIMITATIONS.md. Quote verifiability: 19.39% of rows have a provenance quote whose own source text is still available and re-checkable. Scientific fidelity is unmeasured. All QA verifies well-formedness, not whether a finding correctly interprets its source. Treat every row as a pointer to a paper to read. Paper flags: includes annotations/paper_flags.csv, which marks 3 retracted papers, 0 correction notices extracted as papers, 42 papers with a published correction and 5 duplicate records (preprint and published versions, co-publications). Exclude or count them as the file recommends; no row was removed. Checked against PubMed and Crossref on 2026-10-26. Not medical advice.
