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: This study aimed to analyze the clinical characteristics and rate of transfusion related adverse reactions (TRARs) in pediatric patients with malignant solid and hematological tumors. Materials and methods: A retrospective analysis was conducted on 34,195 blood transfusions (RBC: 41.0%; PLT: 40.7%; FFP: 16.0%; cryoprecipitate: 2.3%) among 9,129 pediatric patients. TRARs were classified and severity graded according to the Chinese Haemovigilance Network criteria. Statistical comparisons were made between serious ( Results: The overall TRAR rate was 680/100,000 (231/34,195), with PLT-associated TRARs being most frequent (1,250/100,000, 174/13,915). Allergic transfusion reactions (ATRs) dominated (95.7%, 221/231), followed by febrile non-hemolytic reactions (FNHTRs, 3.5%, 8/231). Serious TRARs (16.0%, 37/231) primarily involved ATRs (91.9%, 34/37), presenting with respiratory/gastrointestinal symptoms (41.2%) or anaphylactic shock (14.7%). After adjustment for multiple comparisons using the Bonferroni correction, prophylactic premedication was significantly associated with the occurrence of serious TRARs ( Conclusion: Pediatric patients with malignant solid and hematological tumors exhibit a high TRAR incidence, particularly with PLT transfusions. ATRs constitute the majority, underscoring the need for vigilant monitoring and evidence-based prophylaxis. The inefficacy of routine premedication raises important questions about tailored transfusion strategies. Further research is warranted to optimize platelet product selection and TRAR management protocols in this vulnerable population.
