Multivariate logistic regression models were used to identify the determination of the regression of IMT of ≥0.10 mm from baseline at the end of the study. ACE/ARB, angiotensin-converting enzyme/angiotensin II receptor blocker; BP, blood pressure; IMT, intima-media thickness; eGFR, glomerular filtration rate; OHA, oral hypoglycemic agents.
