FIGURE 1.

The associations of primary α-linolenic acid–containing foods with intermediate and advanced AMD. Each food was modeled as a continuous variable in a multivariate Cox regression model that included age (continuous), race (Caucasian or not), BMI (in kg/m²: <18.5, 18.5–23, 23–25, 25–30, 30–35, or >35), pack-years of smoking (never, 1–9, 10–24, 25–44, 45–64, or ≥65 y), physical activity (<3, 3–8.9, 9–17.9, 18–26.9, or ≥27 h metabolic equivalent tasks/wk), current aspirin use (≥1 tablet/wk or none), history of hypertension, history of hypercholesterolemia, and total calories (quintiles). In the Nurses’ Health Study, models were additionally adjusted for postmenopausal status and menopausal hormone use (never, current, and past). AMD, age-related macular degeneration.
