N = Sample size, CI = Confidence Interval, CKD = Chronic Kidney Disease, Serum Creat = Serum Creatinine, Creat. Clear. = Creatinine Clearance, GFR = Glomerular Filtration Rate, TC = Total Cholesterol, TG = Triglyceride, HDL-c = High Density Lipoprotein cholesterol, LDL-c = Low Density Lipoprotein cholesterol, VLDL-c = Very Low Density Lipoprotein cholesterol, TSH = Thyroid stimulating hormone, FT3 = Free triiodothyronine, FT4 = Thyroxine   Result is presented as mean ± standard deviation. *P-values less than 0.05 were considered statistically significant.
