Fig. 3From: Factors affecting the relationship between ionized and corrected calcium levels in peritoneal dialysis patients: a retrospective cross-sectional studyRelationship between iCa and cCa in higher and lower weekly renal Kt/V groups. In both groups, iCa and cCa were directly correlated (r = 0.80, p < 0.01 and r = 0.86, p < 0.01 for the higher and lower renal Kt/V groups, respectively). At the same cCa levels, patients with lower RRF had lower iCa levels than those with higher RRFBack to article page
