Incidence rates and hazard ratios of ischemic stroke after the initiation of conventional and atypical antipsychotic medications.

(SMR, standardized morbidity ratio)* (No. of events/total No. of days per 365 days)× 1,000.† Adjusted for age, gender, presence or absence of dementia (F00-F03, G30, G31.8), depression (F32–33, F34.1, F41.2), dyslipidemia (E78.0), coronary heart disease (I21-I25), COPD (J40-J44, J47), and the use of antidepressants, benzodiazepine, anticoagulants, or antithrombotic agents during the follow-up period.SMR weighted and multivariable adjusted HR after exclusion of the patients whose propensity score was > 99.99 in quetiapine, 0.90 in haloperidol, and Incidence rates and hazard ratios of ischemic stroke after the initiation of conventional and atypical antipsychotic medications.
