Figure 2. Time to first disease relapse during the 2-year study period among all patients. Patient claims were analyzed for disease relapse after switching antipsychotic medication. Outcomes for both cohorts (those who switched, and those who did not) were assessed using Kaplan–Meier analysis and compared using a log-rank test. The number of patients at risk is represented for each time point. Abbreviations. CI, confidence interval; HR, hazard ratio.
Figure 3. Time to first psychiatric admission during the 2-year study period among all patients. Patient claims were analyzed for first psychiatric admission following switching of antipsychotic medication. Outcomes for both cohorts (those who switched, and those who did not) were assessed using Kaplan–Meier analysis and compared using a log-rank test. The number of patients at risk is represented for each time point. Abbreviations. CI, confidence interval; HR, hazard ratio.
Figure 4. Time to first IP admission during the 2-year study period among all patients. Patient claims were analyzed for IP admission following switching of antipsychotic medication. Outcomes for both cohorts (those who switched, and those who did not) were assessed using Kaplan–Meier analysis and compared using a log-rank test. The number of patients at risk is represented for each time point. Abbreviations. CI, confidence interval; HR, hazard ratio; IP: inpatient.
