Agreement between predicted hand bradykinesia score and live rater’s hand bradykinesia score. Each point corresponds to one subject visit, solid line represents line of best fit and shaded region represents the confidence interval. Hand bradykinesia score (range: 0–12) is a composite score derived by taking the sum of finger tapping (MDS-UPDRS 3.4), hand movement (MDS-UPDRS 3.5) and hand pronation-supination (MDS-UPDRS 3.6) scores.
