Data extraction

• 1:25The extraction gridA studies-by-endpoints matrix shows what data exists, is partial, or is missing across the review.
• 1:24Field-level evidenceEvery extracted value carries its page, confidence, and source sentence — inspectable in the document.
• 1:15Value provenanceAn expandable record shows each step behind a value, and whether it is validated or machine-read.
• 1:34Correcting a valueEdit a wrong number in place beside its evidence; the change is saved as a distinct human edit.
• 1:28Missing data, countedGaps keep their rows and get explained — a paper reporting nothing is stated, not hidden in a blank cell.
