The original version of this Article contained an error in the Discussion section,


“As we have previously commented in relation to the PREVENTT trial25, this might lead to statistical underpowering of these trials in the evaluation of the effect of pre-operative iron. Of note, in the trial by Richards et al.16, proportions of iron deficient-patients were of 28% and 29%, depending on the group.”


now reads:


“As we have previously commented in relation to the PREVENTT trial25, this might lead to statistical underpowering of these trials in the evaluation of the effect of pre-operative iron.”


The original Article has been corrected.
