Figure 3:

Risk of arterial thrombotic events after non-traumatic subdural hemorrhage, stratified by indications requiring antithrombotic therapy. Cox regression model showing the risk of an arterial ischemic event with corresponding survival probabilities after non-traumatic subdural hemorrhage (Panels A and B), compared to those without subdural hemorrhage (Panels C and D). Models adjusted for demographics, vascular risk factors, and Charlson comorbidity indices.

Abbreviations: CI, confidence interval; SDH, subdural hemorrhage.

Note: Hazard ratio of 0 indicates very few events in the specified time interval.
