A–K: HRs based on cubic splines for the association between quintile of vegetable/potato intake (g/day) with incident diabetes among participants in the DCH study (N = 54,793): GLV (A), cruciferous vegetable (B), red/orange vegetable (C), other vegetable (D), legume (E), allium (F), all potato (except fries/chips) (G), boiled potato (H), roasted potato (I), mashed potato (J), and potato fries/chips (K) intake. HRs are based on a Cox proportional hazards model adjusted for sex, age, physical activity, smoking status, alcohol status, education level, and hormone replacement therapy and compare the amount of vegetable/potato intake with the median intake in Q1. The χ2 test was used to obtain P values for nonlinearity comparing the nested models.
