Absolute blood (a), and plasma volume (b), as well as masses of total Hb (c), sTfR (d), serum hepcidin (e), and serum iron (f) in NW and OW/OB. Error bars are means ± SDs (for absolute blood, and plasma volume, total mass of Hb, serum iron and hepcidin) or geometric means (95% CIs) (for sTfR). Comparisons between NW and OW/OB was assessed with independent samples t-test. NW normal-weight group (n = 24), OB/OW overweight/obese group (n = 38). *P < 0.05; **P < 0.01; ***P < 0.001
