9.2. Efficacy
9.2.1. Primary efficacy
Through the course of the 6-week study, the psychotic symptoms of
subjects were reduced and the primary parameters were significantly
improved compared with baseline (all p values b 0.01) in both the
aripiprazole and risperidone treatment groups (Fig. 2A). Rapid onset
of efficacy with statistically significant improvement as early as week
1 (p values b 0.01 against baseline) (Fig. 2A) was observed. There
were no significant differences in the change of PANSS total scores
between the aripiprazole and risperidone groups throughout the scheduled
visits after randomization (Fig. 2A).
