Blood donor deferral patterns in Iran: six-year national analysis (2016-2021).
Article in Blood transfusion = Trasfusione del sangue. 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
backgroundBlood donor deferral has a significant impact on the adequacy of blood supply and donor retention globally. Understanding deferral patterns is crucial for optimizing donation services and ensuring a sustainable blood supply in middle-income countries with established voluntary donation systems. The aim of this study was to analyze the prevalence, temporal trends, and causes of blood donor deferrals across Iran using a comprehensive 6-year national dataset (2016-2021). MATERIAL AND
methodsWe conducted a retrospective analysis of all voluntary blood donation attempts recorded in Iran's "Negareh" database (2016-2021). Data included demographics, donation history, deferral status, and provincial variations. Non-parametric tests and chi-square analyses were performed (p<0.05).
resultsAmong 12,966,574 donation attempts, 2,161,808 individuals (16.67%) were deferred: 14.37% temporarily and 2.30% permanently. Deferral rates varied significantly by experience: 32.19% for first-time donors, 18.18% for repeat donors, and 8.98% for regular donors (η DISCUSSION: Iran's 16.67% deferral rate falls within global ranges but shows potential for optimization. The predominance of temporary deferrals (86.2%) and their association with modifiable factors suggest that targeted interventions could reduce deferrals by 2-3% while maintaining safety. Gender-specific prevention of anemia, enhanced preparation of first-time donor, and province-specific approaches could improve the donor experience and blood supply sustainability.
