Scoped audit evidence

These are source- and component-level audit summaries as of 3 October 2026. Access and comparison scope can differ by report; none certifies every result or the underlying raw data.

Parkinson’s disease — transfer

Protocol: 43-cm armless chair, crossed arms, full upright stand, start command to fifth buttock contact. Clinical n=80, reliability n=10; seven failures assigned 60 s. ICCs .99/.76; correlations −.71/.55/−.33; model R² .528 then .555. Retrospective repeat-faller threshold 16 s: AUC .77, sensitivity .75, specificity .68. One main-cohort trial differs from the two-trial reliability procedure.

Limitations: Only the enumerated transfer-relevant components were adjudicated. Source availability does not imply every statement, supplement, figure or raw datum was checked.
