Stepwise Regression Model for Functional Outcome in Acute Ischemic Stroke Population With rtPA and TIA.^a

Variables	B Value	Wald	Odds Ratio	95% CI	P Value
Female	−0.773	4.336	0.462	0.223-0.956	.037b
History of stroke	1.172	8.88	3.229	1.494-6.98	.003b

Abbreviations: CI, confidence interval; OR, odds ratio; rtPA, recombinant tissue plasminogen activator; TIA, transient ischemic attack.

^a Clinical factors that were associated with an improvement in ambulation for ischemic stroke population with rtPA and TIA. Adjusted OR < 1 denote factors that are associated without an improvement in ambulation, while OR > 1 denote factors that are associated with an improvement in ambulation. Hosmer-Lemeshow test (P = .522), Cox and Snell (R ² = .101). The overall classified percentage of 63.4% was applied to check for fitness of the logistic regression model. 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

^b Statistical significance (P < .05) with a 95% confidence interval.
