TF and anemia (phenotype): Anemia correlated positively with changes in BMI z-score (r = 0.434, p < 0.001), weight (r = 0.324, p < 0.001), serum albumin (r = 0.288, p < 0.001), and cholesterol (r = 0.398, p < 0.001), but correlated negatively with serum calcium (r = −0.403, p < 0.001), iPTH (r = −0.616, p < 0.001), ferritin (r = −0.119, p = 0.019), and transferrin saturation (r = −0.253, p < 0.001) (Table 7).
