Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); CHD, coronary heart disease; OR, odds ratios.
Adjusted for age and sex plus 10 genetic principal components, assessment center, and batch effects.
Additionally adjusted for smoking history, alcohol intake, and Townsend scores.
Significant at P < .01.
Additionally corrected for use of antihypertensive medication; reported as unstandardized β coefficient.
