Impacts of donor age and HLA mismatch on HCT outcomes differ according to the donor CMV serostatus in unrelated allo-HCT.
Article in Blood advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
abstractIn unrelated allogeneic hematopoietic cell transplantation (allo-HCT), older and/or HLA-mismatched donors are known risk factors for survival outcomes. In healthy individuals, cytomegalovirus (CMV) seropositivity is associated with impaired adaptive immune systems. We assessed whether the adverse effects of donor risk factors are influenced by the donor CMV serostatus. We analyzed 5836 patients with CMV seropositivity who received unrelated allo-HCT. We divided the entire cohort into 2 cohorts according to the donor CMV serostatus: CMV positive (DP) and negative (DN). We also stratified each cohort into 4 groups based on donor age (aged ≥40 or <40 years) and HLA parity (8/8 or 7/8): Young88 and Old88, and Young78 and Old78, respectively. In the CMV-DP cohort, the Old88 (hazard ratio [HR], 1.20; P = .012), Young78 (HR, 1.35; P < .001), and Old78 (HR, 1.60; P < .001) groups were associated with inferior overall survival (OS) than the Young88 group. In contrast, in the CMV-DN cohort, neither donor age nor HLA disparity was associated with inferior OS. The adverse impact of donor age was different between the cohorts (CMV-DP: HR, 1.19; P = .001; CMV-DN: HR, 1.04; P = .53; P for interaction, .070), as was the impact of HLA (CMV-DP: HR, 1.34; P < .001; CMV-DN: HR, 1.08; P = .23; P for interaction, .012). The impacts of donor age and HLA mismatch on OS might differ according to the donor CMV serostatus. In unrelated allo-HCT from a CMV-seronegative donor, an HLA-mismatched older donor may be able to be selected without affecting OS.
