Table 6.

Accuracy (%) of alternative models. TUG-only and cogTUG-only models used features derived from the first trial, the second trial, and the mean of corresponding features from both trials. TUG-duration and cogTUG-duration models used the durations of TUG and cogTUG tasks. The numbers in parentheses represent the difference in accuracy between the respective model and the corresponding all-task (standard) model (same row).

	All Tasks	TUG-Only	cogTUG-Only	TUG-Duration	cogTUG-Duration
All PD vs. controls	92.6	90.1 (−2.5)	89.4 (−3.2)	83.3 (−9.3)	84.0 (−8.6)
Mild PD (H&Y ≤ 2) vs. controls	89.4	77.9 (−11.7)	87.2 (−2.4)	78.7 (−10.7)	77.0 (−12.4)
