The normally distributed data were expressed as mean ± SD (t-test). The non-Gaussian data were presented as median (range) (Mann–Whitney test). MCV: mean corpuscular volume; MCH: mean corpuscular hemoglobin; MCHC: mean corpuscular hemoglobin concentration; TIBC: total iron binding capacity; TS: transferrin saturation; TC: total cholesterol; LDLc: low-density lipoprotein cholesterol; HDLc: high-density lipoprotein cholesterol; TG: triglycerides; hsCRP: high sensitivity C-protein reactive; nPCR: normalized protein catabolic rate.
