Remarkably, TGF-β1 was associated with the presence of carotid plaque not only after adjustment for demographics (age, sex, body mass index, diabetes, hypertension, and aspirin use) but also after adjustment for relationships of TGF-β1 with lipid profile molecules, insulin resistance, and SLEDAI disease score (odds ratio 1.14 [95% confidence interval 1.003–1.30], p = 0.045). Here, TGFB1 is linked to diabetes mellitus.
