Model 1: adjustment for age, race, sex, education, income and geographic region of residence.
Model 2: adjustment for Model 1 variables plus high-density lipoprotein and total cholesterol, c-reactive protein >3 mg/L, systolic and diastolic blood pressure, antihypertensive medication use, albumin-to-creatinine ratio ≥30 g/mg and estimated glomerular filtration rate <60 ml/min/1.73 m2.
Quartiles determined using all participants.
Mediterranean diet score cut-points: [quartile 1 (low) to quartile 4 (high)] <3, 3 to <4, 4 to <6, and ≥6.
Number of healthy lifestyle factors: the sum of a non-obese waist circumference (<102 cm for men and <88 cm for women), physical activity ≥ 5 times per week, nonsmoking, saturated fat intake < 7.0% of average daily calories and Mediterranean diet score in quartile 4.
