Virkningen blev hovedsagelig bedømt ud fra antallet af patienter, hos hvem transplantationen mislykkedes (f. eks. vurderet efter, om det var nødvendigt at gentage transplantationen eller genoptage dialysen) efter et års behandling.
The main measure of effectiveness was the number of patients in whom the transplant failed (as measured by looking at, for example, the need for a repeat transplant or a return to dialysis) after one year’ s treatment.
