Provenance

Field provenance follows the dataset contract: values are source-qualified, and records not cleared for the paid release stay out of commercial snapshot/API responses. Each release probes a bounded sample of this field's advertised evidence links; the check outcome is shown here, and a link that did not resolve renders as UNVERIFIED rather than as resolved.

RESOLVEDevidence link: 21 sampled clinicaltrials-gov/drks/isrctn links resolved at the 2026-11-02 check
