Frequency of Vitamin D deficiency and its association with serum PTH levels in end stage renal disease patients

To assess the frequency of Vitamin D Deficiency and its association with serum Parathormone (PTH) levels in End stage renal disease patients in a tertiary setup. This cross sectional study was conducted in the Department of Nephrology, Liaquat National Hospital from January to December 2016 and comprised patients with End stage renal disease on maintenance haemodialysis.

To determine association between Vitamin D and serum Parathormone (PTH) levels chi-square test was applied. Association of serum alkaline phosphatase levels with both Vitamin D levels and PTH levels was analyzed using chi-square test. SPSS 20 was used for data analysis. P-value
