Fig. 5 — a Well predicted serum metabolites by the gut microbiome composition (R2 > 0.05 in the training set) and (b) poorly predicted serum metabolites (R2 < 0.05 in the training set) mean observed change (x-axis) and mean predicted change (y-axis) over this study participants per metabolite (dot). Stratified by the dietary intervention, “PPT diet” in orange and “MED diet” in blue, and sized in (a) by the coefficient of determination (R2) of each metabolite in the training set. r, p in the legend—Pearson correlation between the mean observed and mean predicted change in each diet.
