The patients for whom SC was activated during the study duration were included in the study if (1) they aged ≥18 years; (2) Magnetic resonance imaging (MRI) of the brain was done for ischemic stroke evaluation provided that the computed tomographic (CT) scan was negative for hemorrhage.
The patients were classified to have a stroke only if they had a “definite stroke,” i.e., the clinical picture of an acute vascular event was supported by the neuroimaging evidence. 6 Those diagnosed as a transient ischemic attack (TIA) were excluded from the study. Subarachnoid hemorrhage and subdural hemorrhage as well, were not considered stroke for the purpose of our study and hence excluded. 7
