Skolarus et al. (2013) conducted a cohort in Acute ischemic stroke (n=1,791). Body mass index vs. Other BMI categories was evaluated on Mortality (p=<0.01). In 1,791 patients with acute ischemic stroke (35% overall mortality), the relationship between BMI and mortality was U-shaped, with the lowest risk at a BMI of ~35 kg/m2.
