SECTM1 and tuberculosis: Figure 9B showed no significant difference in CETP between groups, though trends were consistent with the training set. TYROBP showed no significant difference between the DM and DM–TB groups but was significantly lower in the DM group compared to HCs (p = 0.0022, Figure 9C). SECTM1 expression was significantly higher in DM–TB than in the DM group (p = 0.0089) and significantly lower in the DM group compared to healthy controls (p = 0.0144, Figure 9D).
