A. Treatment change on the MAL (change in MAL mean from baseline) by group during the intervention period (light gray, left) and 6-month follow-up (dark gray, right). MAL mean can range from 0–5 with an MCID of 1 (red dashed line). Error-bars reflect the 95% confidence interval. Statistically significant between-group comparisons are shown with an *. B. Treatment change on the WMFT (natural log transformed) by group during the intervention period (light gray, left) and 6-month follow-up (dark gray, right). The possible range of the natural log transformed WMFT treatment change is −4·78 to 4·78. Log differences in WMFT of −0·2, −0·3, and −0·4 log units reflect 18%, 26%, and 33% improvement, respectively. MAL = Motor Activity Log, WMFT = Wolf Motor Function Test, MCID = Minimally clinically important difference.
