Final linear mixed-effects model results summary (random effects), across all skill domains^a,b.

Predictors			Variance (SD)		Correlation
Random effects
	Residual	1.4×10−2 (1.2×10−1)		N/Ac
	Patient (intercept)	2.2×10−3 (4.7×10−2)		N/A
	Domain (intercept)	1.3×10−3 (3.6×10−2)		N/A
	Week:patient (slope)	1.5×10−5 (1.2×10−2)		5.2×10−1
	Week:domain (slope)	1.6×10−5 (4.0×10−3)		3.0×10−2

^aN (total observations)=111,768; N (patients)=2249; N (domains)=13.

^bModel equation: domain score (weekly average) ~ week × (dosage group + total hours) + baseline domain score + age + sex + chronicity + (1+ week:patient) + (1+ week:domain).
