Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); hsCRP, high sensitivity C-reactive protein; NA, not applicable; PCE, pooled cohort equations.
Atherosclerosis Risk in Communities, Coronary Artery Risk Development in Young Adults, and Cardiovascular Health Study.
Dallas Heart Study, Framingham Heart Study Third Generation, Jackson Heart Study, Multi-Ethnic Study of Atherosclerosis, and Reasons for Geographic and Racial Differences in Stroke.
Hazard ratios per 1-SD change in the exposure, with the addition of each obesity-related measure to a standard pooled cohort equation–based risk-estimation model.
