Association of Donor and Recipient Duffy and Kidd Genotypes with GVHD in Leukemia Patients Undergoing Bone Marrow Transplantation.
Article in Iranian journal of pathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background & Objective: Graft-versus-host disease (GVHD) is a major complication following allogeneic bone marrow transplant (BMT), often limiting therapeutic success in leukemia patients. Chemokine receptors, such as those encoded by Duffy (FY) and Kidd (JK) blood group genes, may influence GVHD development by modulating immune cell trafficking. To evaluate the association between donor and recipient Duffy and Kidd genotypes and GVHD incidence in leukemia patients undergoing HLA-identical sibling BMT. Methods: This retrospective cross-sectional study analyzed 100 DNA samples from 50 donor-recipient pairs (20 with GVHD, 30 without). Genotyping for FY and JK antigens was conducted using PCR-RFLP. Statistical analysis was performed using chi-square and logistic regression tests in SPSS v19, with significance set at P < 0.05. Results: Kidd and Duffy genotype distributions differed between BMT recipients who developed GVHD and those who did not. However, when gender was included as an additional variable, these associations in recipients were no longer statistically significant for either genotype. In donors, neither the Kidd nor the Duffy genotypes showed a significant association with GVHD status overall. Interestingly, when stratified by gender, a significant difference was observed only for the Kidd genotype in donors of GVHD-positive recipients, but not in donors of GVHD-negative recipients. However, multivariate logistic regression did not confirm any independent association between Kidd or Duffy genotypes and GVHD in recipients (OR = 2.94, 95% CI: 0.494-17.49, P = 0.236) or donors (OR = 2.273, P = 0.323). Conclusion: Kidd and Duffy blood group phenotypes may influence susceptibility to GVHD. Understanding this relationship can support better donor-recipient matching in BMT.
