a Alpha: the ratio of the two penalties (L1 and L2) in elastic net regression; AUC: area under curve; ROC: receiver operating characteristic

Supplementary Figure 2. The significance threshold for all the 193 food intake variables at 6 different alpha values of the elastic net model a

a Threshold: percentage of the standardized regression coefficients of each food intake variable, which was non-zero in the bootstrap samples; α: the ratio of the two penalties (L1 and L2) in elastic net regression
