Metabolite prediction. Microbial abundances (light red) and bacterial pathways (dark red) show the largest potential to predict the levels of metabolites. Boxplots show the ability to predict metabolites levels of eight different models using seven types of data. Dots represent metabolites, and values in the y-axis represent the percentage of variation explained from cross-validated penalised regression methods using different sets of predictors (see online supplemental methods). The number of features in each model are indicated in parentheses in the legend (online supplemental table 20).
