Survival rates: time to all-cause medication discontinuation for clozapine, olanzapine, risperidone, quetiapine, ziprasidone versus typicals. Abbreviations: CLZ, clozapine; OLZ, olanzapine; RIS, risperidone; QUE, quetiapine; ZIP, ziprasidone. Significant differences between CLZ, OLZ, and RIS versus the combined typicals at p < .05 using the Cox Proportional Hazards regression model adjusted for patients and prior treatment characteristics.
