Table 4.
Pearson correlation coefficients (with p-values) for the longitudinal analysis (n = 29, except for delta mycophenolate dose, for which n = 22). Boxes shaded orange indicate a statistically significant positive correlation, and boxes shaded blue indicate a statistically significant inverse association. Hb: hemoglobin; SDS: standard deviation score; eGFR: estimated glomerular filtration rate; EPO: erythropoietin; ERFE: erythroferrone; tFGF23: total fibroblast growth factor 23; iFGF23: intact fibroblast growth factor 23
