Median time after transplant needed to reach different hemagglutinin titer endpoints
| Titer endpoint . | Median (range) days among those reaching endpoint (number of patients) . | ||
|---|---|---|---|
| MRD . | MUD . | P value* . | |
| IgG-undiluted | 38 (9-101) (n = 99) | 30 (8-151) (n = 169) | <.001 |
| IgM-undiluted | 47 (9-143) (n = 82) | 32 (9-205) (n = 133) | .004 |
| IgG/IgM-nil | 61 (10-182) (n = 44) | 46 (10-172) (n = 76) | .016 |

For HLA-matched related (MRD) and HLA-matched unrelated donors (MUD) among patients reaching the endpoint. (“IgG-undiluted”), days after transplant when IgG-hemagglutinins were only detectable in undiluted serum; (“IgM-undiluted”), days after transplant when IgM-hemagglutinins were only detectable in undiluted serum; (“IgG/IgM-nil”), days after transplant when IgG plus IgM-hemagglutinins were undetectable.
From the Wilcoxon rank sum test.
