So what we performed is that we had already evaluated the prognostic value of the European Leukemia 2022 risk classification in allografted AML patients. And when we performed a single-centre study that was published this year, what we observed initially is that the adverse risk group could be divided in two different groups with really different outcomes. But this study lacked loads of patients and MRD assessment was also lacking. So we performed a validation in 16 centers within Spanish institutions. We had a total number of 651 patients and with these numbers we were able to validate the fact that the adverse risk group can be divided in two different subgroups with really different outcomes in allografted AML patients. Also what we observed is patients located in the adverse risks that do not have really adverse abnormalities, have similarities to the intermediate risk group and this might also offer new therapeutic strategies for those patients that have the worst outcome.
