Ischemic stroke with a preceding Trans ischemic attack (TIA) less than 24 hours and thrombolytic therapy

BMC Neurology

Table 4 Clinical factors that were associated with receiving rtPA for ischemic stroke population past-TIA. Adjusted OR < 1 denote factors that are associated with not receiving rtPA while OR > 1 denote factors that are associated with receiving rtPA. Hosmer-Lemeshow test (P = 0.006), Cox & Snell (R² = 0.102). The overall classified percentage of 70.2% was applied to check for fitness of the logistic regression model. *Indicates statistical significance (P < 0.05) with a 95% confidence interval

Notes
Backward Stepwise model based on Likelihood Ratio was applied
Model assumptions were fulfilled
Multicollinearity and interactions among independent variables were checked and no significant interactions were found
