Multivariable logistic regression model for the predictive factors of serious intracranial cause in acute nontraumatic headache.
| Variables | Crude OR (95% CI) | Adjusted OR (95% CI) | value |
| Abrupt onset | 3.19 (1.9–5.33) | 7.96 (2.77–22.91) | <0.001 | Awakening pain | 7.24 (4.26–12.29) | 3.14 (4.15–6.82) | 0.004 | Duration >1 week | 4.06 (2.12–7.78) | 10.59 (2.9–38.7) | <0.001 | Fever | 4.36 (2.33–8.15) | 6.01 (2.07–17.46) | <0.001 | Worst headache ever | 35 (17.57–69.71) | 12.95 (5.69–29.45) | <0.001 | Alteration of consciousness | 40.33 (11.74–138.6) | 13.55 (2.07–88.88) | 0.002 | Localizing neurological deficit | 8.36 (3.96–17.63) | 5.28 (1.6–17.46) | 0.019 |
