a Area under the ROC curve (AUC) for the GWG group. The blue line indicates the random forest model based on all OTUs, and the red line indicates the random forest model with added PBMI compared with the former model. Each AUC was calculated based on two groups of individuals who were higher or lower than a certain GWG value (e.g., one was <5 GWG, the other was >5 GWG value). The bar plot shows the distribution of GWG values in all samples. b, c Comparison of the OTUs and KEGG modules between the pregnant women with the lowest and highest GWG.
