Identification of microbial markers of FANM by random forest models. (A): A tenfold cross-validation on a random forest model between 40 FANM and 40 control in the training set; (B) Top 14 differentially abundant genera markers were selected as the optimal marker set based on random forest. The x-axis presents the mean decrease accuracy to each marker, which indicates the contribution to the accuracy of the model; (C): The POD value in FANM versus control in the validation set; (D): The POD value in FANM versus control in the testing phase; (E): The AUC value between FANM and control in the validation phase.
