¹All values are RRs; 95% CIs in parentheses.

²Multivariable model was adjusted for age, race, family history of diabetes, BMI (in kg/m²) categories (<23.0, 23.0–24.9, 25.0–29.9, 30.0–34.9, or ≥35.0), smoking status [never, past, or current (1–14, 15–24, or ≥25 cigarettes/d)], alcohol intake (never or <5.0, 5.0–15.0, or ≥15.0 g/d), menopausal status and hormone use, oral contraceptive use, physical activity level (<3.0, 3.0–8.9, 9.0–17.9, 18.0–26.9, or ≥27.0 metabolic equivalent task hours per week), and Alternative Healthy Eating Index (quintiles).

³Calculated by treating plain-water intake as a continuous variable.
