Indirect presentation of mismatched human leukocyte antigen-B associates with outcomes of cord blood transplantation.
Article in British journal of haematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cord blood transplantation (CBT) is a valuable donor source for patients without human leukocyte antigen (HLA)-matched donors. While CBT has a lower risk of graft-versus-host disease and requires less stringent histocompatibility, it is associated with a higher transplantation-related mortality (TRM) compared to other donor sources. We hypothesized that assessing the immunogenicity of mismatched HLA could reveal non-permissive mismatches contributing to increased TRM. We retrospectively analysed 1498 single-unit CBT cases from 2000 to 2018 across eight Japanese institutions, evaluating the immunogenicity of mismatched HLA using the PIRCHE algorithm to examine binding affinities of HLA-derived epitopes to donor or recipient HLA. Results indicated that Class I epitopes from mismatched recipient HLA-B were significantly associated with poor outcomes due to higher TRM and lower neutrophil engraftment, particularly when presented on matched HLA class I. Notably, epitopes from HLA-B exon 1 showed stronger prognostic significance, with HLA-B alleles carrying M-type leader peptides exhibiting higher affinity for these epitopes. Patients with a matched M-type HLA-B and Class I epitopes derived from mismatched HLA-B exon 1 had worse outcomes. These findings suggest that immunogenicity-informed donor selection could improve CBT outcomes.
