Figure 1. Adjusted probability of death in admitted vs discharged patients with TIA or minor stroke and cumulative incidence of recurrent stroke/TIA in admitted vs discharged patients.

(A) Adjusted probability of death in patients with TIA or minor stroke admitted to the hospital or discharged from the emergency department. Adjusted for index event type (TIA vs minor stroke), age, sex, area of residence, disability before event, diabetes, hypertension, hyperlipidemia, dementia, smoking, atrial fibrillation, coronary artery disease, prior stroke/TIA, presenting symptoms (weakness, speech deficit, duration of symptoms, blood pressure), and hospital characteristics (stroke center, teaching status, size). The p value = 0.15 for difference between discharged and admitted patients, based on Cox proportional hazards model. (B) Cumulative incidence of recurrent stroke/TIA in admitted vs discharged patients. Cumulative incidence of recurrent emergency department visit or hospitalization for stroke/TIA within 1 year of the index event in patients with minor ischemic stroke/TIA admitted to the hospital vs discharged from the emergency department. Figures constructed using cumulative incidence functions that account for the competing risk of death. For difference between discharged and admitted patients, p < 0.001, using Gray's test for equality of cumulative incidence functions.
