AGTR1 and diabetes mellitus: The multivariate logistic regression analysis showed that AGTR1 genotype of GA or AA was independently associated with lower risk of LVH (OR = 0.344, 95% CI 0.160 ~ 0.696, P = 0.003) and arterial stiffness (OR = 0.371, 95% CI 0.155 ~ 0.885, P = 0.025) after adjusting gender, age, and diabetes (Table 4).
