Each ‘one-way’ is a transplant from a donor to a patient who are tissue compatible, and the NKR’s matching software combines one-ways into ‘clusters’. The higher the DMP, the more likely the donor paired to the patient will bring the patient into a cluster. DMP is calculated as the percentage of unmatched recipients (exclusive of WLPs) in the NKR pool with whom the donor is both tissue compatible and preference compatible, times 100.
