WebApr 11, 2024 · Biomarkers were finally identified as the overlapping taxa among LefSe and MaAsLin analysis results. Based on differential taxa and clinical variables, random forest classifiers were trained on data from the discovery cohort. Five-fold cross-validation was used to evaluate the performance of the predictive model.
