CRP and diabetes mellitus: A full model using multivariate logistic regression showed that the independent association factors were age (OR 1.04, 95% CI 1.00–1.07), diabetes duration (OR 1.06, 95% CI 1.02–1.10), current smoking (OR 3.14, 95% CI 1.33–7.39), hs-CRP (OR 1.29, 95% CI 1.08–1.54), and YZ score (OR 1.10, 95% CI 1.00–1.21).
