Table 3 Clinical factors that were associated with rtPA for ischemic stroke population with recent-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 = 0.016), Cox & Snell (R2 = 0.679). The overall classified percentage of 96.1% 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
