Serum Biomarkers for Chronic Renal Failure Screening and Mechanistic Understanding: A Global LC-MS-Based Metabolomics Research

Figure 7

Random forest model of differential metabolites of the RF group vs HC group. (a) and (d) are the classification confusion matrix of random forest models in the training set; (b) and (e) are the classification confusion matrices of random forest models in the prediction set. (c) and (f) are the ROC curves based on the prediction probability of the random forest model. (a), (b), and (c) show the analysis of differential metabolites screened by positive ion mode. (d), (e) and (f) show the analysis of differential metabolites screened by negative ion mode.
