Logistic regression analysis for significant hemorrhage (volume >25 mL)
| Predictive factor | OR (95% CI) | Estimate (SE) | P > Ο2* |
|---|---|---|---|
| Poor pial collateral score | 13.1 (2.84β96.0) | 2.57 (0.860) | .0028 |
| Platelets <200K | 8.14 (1.73β60.3) | 2.10 (0.868) | .0157 |
| Intercept | 0.190 (0.520) | .715 |
Note:βOR indicates odds ratio; CI, confidence interval.
* Variables tested with P > .05 were rejected using backward selection (whole-model test, P < .0001; r2 = 0.202).
