PD-G03 · methodological precision
Classification and audit outcome: methodological precision; supported.
Finding
Wang 2026 consulted internal-validation performance when selecting five rather than six predictors.
Current amendment or qualification
The five-predictor model was selected after consulting the internal-validation C-index; this may make internal performance optimistic. The geographic external cohort remains independent.
Integration note: Internal-validation reuse can bias internal estimates; preserve the distinct geographic external cohort.
Remaining limitation: Internal-validation reuse can bias internal estimates; preserve the distinct geographic external cohort.

Affected reports
Original audit locator(s): gait:P0042; gait:P0083
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.
