Multivariate analysis of prediction of intracranial haemorrhage (n = 48)
| Variable | Regression coefficient | SE | Estimated odds ratio | 95% CI | p Value |
|---|---|---|---|---|---|
| Adjusted R2 (Nagelkerke) = 0.42; area under the ROC curve = 0.82. | |||||
| The two explanatory variables (mean 24 hour systolic blood pressure and a hyperdense artery sign) plus the constant represent the simplest adequate model. | |||||
| CI, confidence interval; HAS, hyperdense artery sign; SBP, systolic blood pressure. | |||||
| Mean 24 hour SBP | 0.075 | 0.025 | 1.078 | 1.027 to 1.131 | 0.003 |
| HAS (0 = no; 1 = yes) | 1.892 | 0.822 | 6.630 | 1.323 to 33.235 | 0.02 |
| Constant | −11.772 | 3.783 | – | – | 0.002 |
