Keep from freezing. Similar treatment effects were revealed on the basis of sensitivity analyses using multiple imputation (365 accelerometer units per day; 95% CI, 754 to 23; P = 0.07), paired t-test crossover analysis (402 accelerometer units per day; 95% CI, 794 to 9; P = 0.04), and analysis restricted to patients who were receiving a study drug during the end-point assessment (306 accelerometer units per day; 95% CI, 745 to 141; P = 0.18). what dose adjustments is recommended?
