Survival rates: time to all-cause medication discontinuation for atypicals versus typicals of different potency levels. Abbreviation: HAL+AC, haloperidol with prophylactic anticholinergics. Significant differences (p < .05) between the combined atypicals versus typicals of high, medium, and low potency, and versus haloperidol with prophylactic anticholinergics, using Cox Proportional Hazards regression model adjusted for patients and prior treatment characteristics.
