Another study [25], which retrospectively studied the associations between blood NfL and disease outcome in a mixed stroke population, including acute cerebral infarction (n = 227), aneurysmal subarachnoid hemorrhage (n = 58), and ICH (n = 29), concluded that blood NfL levels are associated with acute stroke severity, 3- or 6- month functional disability, and mortality. Here, NEFL is linked to stroke disorder.
