To the Editor The study by Dr Muzaale and colleagues,1 analyzing United States data, reported a slightly increased rate of ESRD in kidney donors compared with selected healthy controls. This rate, however, was lower than that reported in the general population. A similar observation was recently reported from Norway.2 Drs Gill and Tonelli3 have outlined some of the limitations of the analyses. We have additional concerns regarding the study design and conclusions.
