Other factors found to be independently associated with hyperphosphatemia were elevations in the transferrin (p = 0.007) and serum albumin levels (p = 0.049) and nPCR (p < 0.001) and decreases in the hemoglobin level (p = 0.015), residual Ccr (p < 0.001), and PD Ccr (p < 0.001) (Table 4). Here, TF is linked to hyperphosphatemia.
