Values are mean (SE) determined using linear regression with robust variance estimators. Means are adjusted for field center, age (years), sex, race/ethnicity (non‐Hispanic whites, blacks, Hispanics and Chinese Americans), education (<high school, high school, >high school), cigarette smoking (never, current or former smokers, and pack‐years of cigarette smoking), alcohol (g/day), physical activity (metabolic equivalents per minute/week), prevalent diabetes (yes, no) alcohol intake (g/day) and BMI (kg/m2). CVD indicates cardiovascular disease; BP, blood pressure; HDL‐C, high‐density lipoprotein cholesterol; LDL‐C, low‐density lipoprotein cholesterol; BMI, body mass index; CRP, C‐reactive protein.
Tests for trend across quintiles were performed by assigning each participant the median fatty acid value in their quintile and modeling this variable as a continuous term.
Included adjustment for antihypertensive medication use at baseline (yes/no).
Included adjustment for lipid‐lowering medication use at baseline (yes/no).
Included adjustment for anti‐inflammatory medication at baseline (yes/no).
