Multivariable Analysis of In-Hospital Mortality and Hematoma Expansion
| Variable | In-hospital death | Hematoma Expansion* | ||
|---|---|---|---|---|
| OR (95% CI) | P–value | OR (95% CI) | P–value | |
| Age | 1.00 (0.96 – 1.05) | 0.90 | --- | -- |
| Sex (male) | 1.70 (0.54 – 5.62) | 0.37 | --- | -- |
| Warfarin | 1.70 (0.28 – 14.00) | 0.59 | --- | -- |
| Time to CTA** | 1.11 (1.02 – 1.23) | 0.02 | 1.10 (1.02 – 1.32) | 0.01 |
| Baseline ICH volume | 1.04 (1.03 – 1.07) | <0.0001 | 1.01 (1.00 – 1.02) | 0.10 |
| Extravasation rate (mL / hour) | 1.09 (1.04 – 1.18) | 0.004 | 1.03 (1.01 – 1.08) | 0.047 |
*
Data refer only to ICH patients with a follow-up CT (n = 125, 77%). Analysis restricted to three covariables based on the rule of one covariate per ten outcome events (n = 26).

Odds ratio for shorter time to CTA
OR = Odds Ratio; 95% CI = 95% Confidence Interval; ICH = Intracerebral Hemorrhage; CTA = CT Angiography; mL = milliliter
