Finding
Current amendment or qualification
The 45-person derivation cohort included 21 fallers. Index D3 was also externally evaluated in a separate 30-person cohort with nine fallers: AUC 0.84 (95% CI 0.68–1.00), sensitivity 0.56 and specificity 0.95 at the prespecified cutoff of 3.5. Index C was assessed in 54 pooled participants, comprising the original 45 plus nine new patients, so that analysis is not independent external validation. A lower D3 cutoff of 2.5 was selected in the validation sample and needs fresh evaluation. These small samples still limit implementation.
Remaining limitation: D3 revised cutoff2.5 was chosen in validation cohort and needs fresh testing. Pooled bootstrap n75 is not the independent-validation denominator.

Audit corrections describe the report only where that classification is explicit. A disagreement within a study, missing protocol, statistical query, access upgrade or optional addition is not silently converted into a report error or a new clinical threshold.
