Table 1 - Mean values of haemoglobin, glomerular filtration rate, ferritin, transferrin, and transferrin saturation 1, 3, 6, and 12 months after the start of PEG-EPO

Results are shown as mean (range). ^aP<.0001 (95% confidence interval [CI] haemoglobin after 3 months -1.9-0.9; 6 months: 0.7-1.9; 12 months: 0.6-1.8). ^bP=.018 (95% CI: 12.3-118.2). ^cP=.032 (95% CI: -40-[-2]). ESA: erythropoiesis-stimulating agent; MDRD-4 (glomerular filtration rate calculated using the MDRD-4 formula); PEG-EPO: methoxy polyethylene glycol-epoetin beta.
