EEF2 and rheumatoid arthritis: According to the results of the ROC curves, the AUC values of EEF2 (0.984), HSP90AB1 (0.971), and TNFSF10 (0.713) were all higher than 0.7 (Figure 5E), and nomogram (AUC = 0.995, 95% CI: 0.988–0.999) exhibited a higher AUC value than each gene (Figure 5F), suggesting that nomogram may possess powerful diagnostic efficacy for RA.
