  • Model adjusted for age, sex, educational attainment, marital status, Hispanic/Latino background, acculturation score, income, health-insurance coverage, smoking status, physical activity level, body mass index, history of hypertension, diabetes, lipids (cholesterol and triglycerides), glycated hemoglobin, systolic BP, diastolic BP, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, baseline kidney-function measures, and study site. AHEI-2010, DASH, and MeDS scores were categorized into quartiles (Q1, Q2, Q3, and Q4). Q1 is the lowest quartile (unhealthiest diet) and Q4 is the highest quartile (healthiest diet).
