Extrapyramidal Side Effects and Other Adverse Events
The frequency of extrapyramidal side effects and other adverse events, scores on the Treatment Emergent Symptom Scale and Simpson-Angus Scale of Extrapyramidal Symptoms, and changes in body weight are shown in Table 4. The proportions of extrapyramidal side effects and other adverse events did not significantly differ among the three groups at the end of the first 4 weeks or at the end of the study (p>0.05), and there were no significant differences in the baseline scores and changes from entry to the end of the study in the scores on the two scales or in body weight. There were no significant differences among the groups in changes on the Simpson-Angus scale score or in body weight during the first 4 weeks, while the increase in the score on the Treatment Emergent Symptom Scale for the 26-week group was significantly greater than for both the 4-week group (95% CI=0.90–2.15, p
