CRP and hypertensive disorder: HbA1c (OR:1.42, CI:1.19-1.70, and OR:1.31, CI:1.12-1.54) and serum Cr (OR:2.93, CI:1.06-8.09, and OR:2.50, CI:1.06-5.88) were significant predictors of both HTN and non-HTN classes respectively, while serum vitamin D and CRP level were no significant predictors of metabolic syndrome classes.
