After publication of this paper, the authors have determined that the forest plots presented are incorrect. Corrected fixed-effects forest plots are found below. However, the information in the text is correct except for the following two points: (1) under the subheading “Associations of rs4820268 with Hb and iron status”, it should read that in Caucasian populations the G allele of rs4820268 results in lower concentrations of Hb by 0.08 g/dL (95 % CI −0.16, −0.01). In the “Discussion”, based on our meta-analyses, the overall effect estimate of the Asian studies indicates that for each G allele of rs4820268 an additional decrease of 0.08 and 3.81 is observed for Hb and ferritin values, respectively (Figs. 2, 3, 4, 5, 6, 7, 8).
