Associations between blood donors, component modifications, and the alloimmunization of transfusion recipients.
Article in Transfusion, 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
backgroundPrior studies have evaluated transfusion recipient variables impacting red blood cell (RBC) alloimmunization, but few focused on potentially modifiable blood donor or blood component variables. STUDY DESIGN AND
methodsData from the Recipient Epidemiology and Donor Evaluation Study (REDS)-III, which links donor, component, and patient data in an integrated database, were accessed. For any given RBC unit with sufficient blood donor and component data, we determined if the transfusion recipient experienced a new RBC alloimmunization event ("case") within 16 weeks of the transfusion or not ("control"). Recipient diagnoses were included in the case-control matching algorithm.
resultsA total of 2676 cases were matched with 10,160 controls. In a multivariate conditional logistic regression analysis, recipients who received an RBC unit from donors with a different ABO group had a higher risk of alloimmunization (OR 1.60, 95% CI: 1.35-1.89, p < .001). Likewise, recipients who received RBCs from older donors had a higher risk of RBC alloimmunization (OR 1.01 per year of age, 95% CI: 1.00-1.01, p < .001). Irradiated RBCs were associated with a decreased risk of RBC alloimmunization in transfusion recipients (OR 0.52, 95% CI: 0.46-0.59, p < .001), though a sub-analysis of RBCs transfused to people with sickle cell disease showed no such association (p = .75). Recipients who received RBCs stored for a longer duration also had a lower risk (OR 0.99 per day of storage, 95% CI: 0.99-0.99, p < .001) of alloimmunization. DISCUSSION: This case-control study identified donor and component variables associated with recipient RBC alloantibody formation. Future mechanistic studies exploring these associations are warranted.
