Multivariate models were adjusted for age, sex, race/ethnicity, smoking status, pack-yrs, urine cotinine, educational attainment, diabetes mellitus, fasting plasma glucose, height, body mass index, hypertension, systolic and diastolic blood pressure, low- and high-density lipoprotein, statin medication, alcohol use, and C-reactive protein.
