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

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

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