Mineral Bone Disorder in Dialysis

This study was conducted with 167 dialysis patients at Erciyes University Faculty of Medicine, Department of Internal Medicine, Department of Nephrology, and Dialysis Unit, with the approval of the Ethics Committee of Erciyes University Medical Faculty (date: 25.09.2019, no: 2019/673).

Patients aged ≥18 years, undergoing dialysis treatment, and having available data on serum calcium, phosphorus, parathormone, albumin, hemoglobin, blood urea nitrogen (BUN), creatinine, and dialysate calcium levels within the last six months were included in the study.
