Fig. 3. Convergent validity of digital composites.

Fig. 3

Digital composite scores vary significantly with MDS-UPDRS pronation-supination (Kruskal–Wallis p = 0.028, n = 76) and toe-tapping (Kruskal–Wallis p = 0.001, n = 78) scores at the baseline visit. Both (a) pronation-supination (Wilcoxon p = 0.02) and (b) toe tapping (Wilcoxon p < 0.001) digital composite scores significantly distinguished between scores of 0 and 1, though, did not differentiate between scores of 1 and 2, or 2 and 3 (sample sizes and summary metrics for each individual clinical score is available in Supplementary Data).
