CRP and diabetes mellitus: As expected, 24 h urinary microalbumin was negatively correlated with bilirubin concentrations (r = -0.13, P < 0.05), HDL-C (r = -0.16, P = 0.01), and total GFR (r = -0.20, P < 0.001) and positively correlated with duration of diabetes, BMI, SBP, WHR, CRP, uric acid, Cr, TG levels (all P < 0.001).
