ROC curve showed that the AUC of SLC24A2 for independently predicting T2D was 0.6856 (Figure 5(d)), while 8-gene model reached 0.8410 in the training set and 0.6712 in the test set, indicating that the LASSO model may be an efficient tool to explore early biomarkers for diagnosis of T2D (Figure 5(c)). The gene discussed is SLC24A2; the disease is type 2 diabetes mellitus.
