CRP and diabetes mellitus: In univariate analysis of the RA sub-cohort (n = 2472), HRs showed that higher age (8.50; 95 % CI 5.13–14.09) and higher CRP (2.00; 95 % CI 1.39–2.88) at baseline significantly increased the risk for CVD, but no statistical significance was observed for sex, total cholesterol at baseline, and diabetes complications (Table 3).
