Study characteristics and quality assessment
| Study (year) | Study design | Patient (n) | Outcomes (mo) | Jadad score |
|---|---|---|---|---|
| Kang (2012) | Retrospective Observational | 236 (SCD = 190, LCD = 46) | Total BMD; Calcium; ionized Calcium; i-PTH; ALP (24 month) | 1 |
| Sanchez (2004) | Prospective study; randomized | 24 (SCD = 10, LCD = 14) | Calcium; ionized calcium; i-PTH; phosphate; ALP (12 month) | 3 |
| Weinreich (1996) | Prospective; randomized; controlled | 64 (SCD = 29, LCD = 35) | Ionized calcium; i-PTH; phosphate; ALP (24 month) | 3 |
| Johnson (1996) | RCT; DB | 22 (SCD = 11, LCD = 11) | Phosphate; magnesium; calcium; ionized calcium; i-PTH; BMD z-score (12 month) | 5 |
RCT = randomized controlled trial; DB = double blinded; SCD = standard calcium dialysate; LCD = low calcium dialysate; BMD = bone mineral density; i-PTH = intact parathyroid hormone; ALP = Alkaline Phosphatase.
