The investigators investigated the predictive ability of clinical and radiological scores, including the Glasgow coma scale (GCS), Hunt-Hess, World Federation of Neurological Surgeons (WFNS), and modified Fisher scales, as well as combined clinical scores such as the VASOGRADE and Ogilvy-Carter rating scales, for 28-day mortality in patients presenting to the emergency department (ED) with non-traumatic subarachnoid hemorrhage (SAH). Specifically, we tested the hypothesis that combined clinical scores are more reliable and superior to non-combined clinical and radiological scores in predicting 28-day mortality in non-traumatic SAH.
