SG-C06 · material methodological qualification
Classification and audit outcome: material methodological qualification; supported material methodological qualification.
Finding
Current amendment or qualification
After excluding six slow walkers, the study also removed intersystem measurement differences beyond ±1.96 SD before its final accuracy analysis. Such trimming can make the retained error distribution and limits of agreement look better than performance on all eligible observations. The reported agreement should therefore be labelled as agreement after participant and measurement-error exclusions.
Remaining limitation: Interpretation that outcome-error trimming can improve retained agreement is methodological reasoning; do not infer its unreported quantitative effect.

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.
