Notes: N in the headers represents the total number of subjects in each respective treatment group within the mITT population. Symptom score was assessed on a 0–5 scale; 0.5 increments were not allowed. Lower score indicates less symptomatology. Baseline was defined as the average of all days during the run-in period. Daily scores were obtained by averaging the morning, afternoon, and evening scores for that day.
