Change in UHDRS Motor Score	0 (0, 0)	0 (-1, 4)	0.0016
Change in UHDRS Chorea Score	0 (0, 0)	0 (0, 1)	0.17
Change in Beck Depression Score	-1 (-3, 0)	0 (-2, 3)	0.0286
Change in UHDRS Behavioral Score (Frequency × Severity)	0 (-4, 2)	-0.5 (-6, 2.5)	0.31

Values shown are medians (25%, 75% percentiles). P-values indicate the significance levels for comparisons by CAG status using Kruskal-Wallis tests for the scores at each visit, and analysis of covariance on the ranks, including the prior visit score, was used for the change scores.
