Poor DR MM is associated with increased severe BOS. Patients with higher degree of HLA-DR MM (2 DR antigen MM, black line) experience severe BOS earlier than did individuals that received lungs from a better HLA-DR matched donor (0 or 1 DR MM, green line), P = 0.021. Numbers of subjects at risk at transplant (Tx), 1, 5, 10, and 15 years posttransplant is on the graphic.
