a, Compared to the original results from the ZOE PREDICT 1 study based on the MetaPhlAn 3 taxonomic profiles22, random forest (RF) models trained on the MetaPhlAn 4 microbiome profiles (n = 1,001 samples) substantially improve classification (circles and right-side y axis) and regression (box plots and left-side y axis) result for a panel of 19 markers representative of nutritional and cardiometabolic health (see Methods). Box plots show the median (center), 25th/75th percentile (lower/upper hinges), 1.5× interquartile range (whiskers) and outliers (points.) b, Panel of the 20 unknown microbial species (uSGBs) showing the strongest overall correlations with the positive (top-half list) and negative (bottom-half list) dietary and cardiometabolic health markers, respectively (FDR < 0.2).
