Data are expressed as mean ± SD. Hb: Hemoglobin, WBCS: white blood cells, PLT: platelets, ESR: erythrocyte sedimentation rate, CRP: C-reactive protein, RBG: random blood glucose. TG: triglycerides, LDL: low density lipoprotein, HDL: high density lipoprotein. P1: Group I vs II, P2: Group I vs III, P3: Group II vs III. P<0.05 is significant. P≤0.001 is highly significant.
