Development and validation of a pediatric transfusion medicine education assessment tool.
Article in Transfusion, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPediatric transfusion medicine presents unique challenges due to differences in pediatric physiology and pathology compared to adults. Research shows that pediatric healthcare professionals have knowledge gaps in transfusion medicine, contributing to suboptimal practice. To address these gaps, Transfusion Camp, a transfusion medicine education program, was adapted to a pediatric-focused curriculum. To assess pediatric learners' knowledge uptake, we aimed to develop and validate the Pediatric Transfusion Knowledge Test. STUDY DESIGN AND
methodsThe BEST TEST-3, a previously validated transfusion medicine knowledge assessment tool, was modified by a multidisciplinary committee of content experts, using a curriculum blueprint for pediatric transfusion medicine consisting of 31 core and 42 extended topics, identified through a previously published national multi-specialty Delphi consensus study. The modified test was administered to 8 novice, 20 intermediate, and 14 expert participants in pediatric transfusion medicine. Data were analyzed using Rasch psychometric modeling to finalize test content.
resultsThe finalized assessment tool included 25 multiple-choice questions, with balanced representation across the cognitive processes outlined in Bloom's taxonomy. Twenty-four questions demonstrated good fit statistics with infit average 0.99 (0.8-1.2) and outfit average 0.96 (0.78-1.22). One question required revision. Question difficulty ranged from -2.78 to 1.61 on the logit scale, with gaps observed for higher-ability test-takers. DISCUSSION: Developing the Pediatric Transfusion Knowledge Test represents a systematic approach to adapting and validating an assessment using a curriculum blueprint and ensuring alignment with educational materials. It adapts an existing assessment and incorporates evidence-based pedagogical principles. This framework can be applied to develop other assessments within medical education.
