The results showed that the predictive performance of the three genes individually for DM–TB was as follows: CETP had an AUC of 0.77 (CI: 0.553–0.987), TYROBP had an AUC of 0.69 (CI: 0.432–0.948), and SECTM1 had an AUC of 0.87 (CI: 0.697–1.000) (Figure 9A). Here, CETP is linked to diabetes mellitus.
