Human umbilical cord mesenchymal stem cells ameliorate liver metabolism in diabetic rats with metabolic-associated fatty liver disease

Figure 6 Importance ranking and receiver operating characteristic curves for key differential metabolites for each group based on the random forest model. A and B: Random forest importance ranking dot plots for key differential metabolites between the different comparison groups. The X axis represents the importance indicator values; C and D: Composite receiver operating characteristic curves generated for key differential metabolites between the different comparison groups based on the random forest model. Control group, n = 8; diabetes mellitus group, n = 6; diabetes mellitus + human umbilical cord mesenchymal stem cells group, n = 5. hUC-MSCs: Human umbilical cord mesenchymal stem cells; DM: Diabetes mellitus; ROC: Receiver operating characteristic; AUC: Area under the curve.
