In the article by Najarian et al,1 the authors evaluated the age-adjusted risk of stroke and population-attributable risk associated with either metabolic syndrome or type 2 diabetes mellitus in a cohort of 2097 adult subjects. Metabolic syndrome was more prevalent than type 2 diabetes mellitus in that study population. In subjects without type 2 diabetes mellitus, metabolic syndrome was an independent risk factor for stroke.
