Data are median (IQ range). PRA was measured to both class 1 and 2 antigens. Allo: the β-score and %PRA were determined 1 year after the initial transplant.
* The difference in the β-score for the PRA groups was significantly different from the 0–9% group, P < 0.05. Auto: autoantibodies and the β-score were determined at 1 year, and values among the antibody status groups were similar. ICA, islet cell antibody.
