↵aAdjusted for age at diagnosis (continuous), total caloric intake (quintiles), smoking status (nonsmoker and smoker), BMI (<25, 25–29.9, and 30+), exercise in MET-h/wk (quintiles), tomato sauce intake (<1 serving/wk, 1–1.99 servings/wk, and 2- servings/wk), α-linolenic acid intake (quintiles), TNM stage (T1, T2, and T3a), Gleason score (<7, 7, >7, unknown), and PSA at diagnosis (<10, 10–20, >20, and unknown).
↵bCut points for quintiles of servings per day refer to the cut points for the baseline year, 1986. The cut points for the quintiles vary over time.
