Biomarkers for the diagnosis of RA. (a) LASSO regression analysis to screen for characterized genes. On the left is a graph of the gene coefficients, and on the right is a cross-validated error plot. (b,c) Candidate characterization genes were screened using SVM-RFE in GSE17755. (d) Boruta’s algorithm for ranking the importance of genes. Green color represents confirmed important genes, red color is confirmed unimportant genes, and yellow color is uncertain genes. (e) Wayne diagrams for LASSO-Logistic, SVM-RFE, and Boruta algorithms.
