Screening for key RNA modification regulators (RMRs) in DCM. A Circle diagram of RMRs at different chromosomal locations. B Tuning feature screening in the LASSO model. C Curve of error versus number of decision trees. Red represents the DCM group, green represents the control group, and black represents all of them. D Results of the Gini coefficient method in random forest classifier. The x-axis indicates the genetic variable, and the y-axis represents the importance index. E Screening plot of key RMRs based on SVM-RFE algorithm. F The Venn diagram showing the 4 RMRs shared by LASSO, SVM-RFE and RF
