Cumulative probability of achieving ANC 500 during the first 77 days after transplantation. (A) Relationship to HLA mismatch (MM) number and direction. The number of patients in each mismatch category known to be alive without ANC 500 at time after transplantation are as follows: 0 MM: day 0, 59; day 21, 33; day 42, 3; 1 bidirectional MM: day 0, 342; day 21, 315; day 42, 33; 2 bidirectional MMs: day 0, 509; day 21, 309; day 42, 52; GVH-O MM: day 0, 57; day 21, 30; day 42, 2; rejection only MM: day 0, 37; day 21, 21; day 42, 8. (B) Relationship to TNC dose × 107/kg.
