FIGURE 1.

Adjusted HRs with 95% CIs for incidence of diabetes by tertile of hPDI (A), uPDI (B), alternate hPDI (C), or alternate uPDI (D). Models adjusted for age, sex, education (<5^th grade, 5^th–8^th grade, 9^th–12^th grade or General Educational Development, some college or more), marital status (married/living as married/spouse in household, married and spouse not in household, divorced/separated, widowed, or never married), income-to-poverty ratio (total household income/threshold dollar amount), total energy (kcal), smoking (<100 cigarettes in entire life, past but not current, or current), alcohol frequency (none, moderate, or heavy), physical activity score, psychological acculturation score, depressive symptomatology score, BMI (kg/m²), hypertension (y/n), plasma cholesterol (mmol/L), and antilipemic agents (y/n). Alternate hPDI and uPDI were calculated by removing tea and coffee from the healthy plant food groups and removing sweets and desserts, and sugar-sweetened beverages, from the unhealthy plant food groups. hPDI, healthful plant-based diet index; uPDI, unhealthful plant-based diet index.
