To the Editor In a meta-analysis, Dr Rohde and colleagues1 summarized the results from 18 randomized clinical trials of the effect of restrictive compared with liberal red blood cell transfusion strategies on the incidence of infections in the recipients. The review included results from a Danish study presented by us in a conference abstract2 on the risk of infection in frail elderly patients with hip fractures after surgery.
