Patients were reclassified according to FAB and then according to WHO. The table shows the reclassified FAB diagnoses. Seven cases were difficult to reclassify according to FAB guidelines and were not possible to classify according to WHO guidelines (ie, no megakaryopoiesis available for evaluation). These patients are listed under their original FAB diagnosis.
