Positive B values (Adj, OR > 1) denote variables more associated with rtPA inclusion while negative B values (Adj. OR < 1) denote variables more associated with rtPA exclusion. Multicollinearity and interactions among independent variables were checked. Hosmer-Lemeshow test (P = 0.854), Cox & Snell (R² = 0.159), classification table (overall correctly classified percentage = 67%) were applied to check the model fitness
