The effect of allogeneic blood transfusion on burn mortality in a resource-limited setting.
Article in Burns : journal of the International Society for Burn Injuries, 2025. 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
introductionThere are nearly 9 million new burn cases worldwide, with a disproportional burn burden in low- and middle-income countries. Patients with significant burn injury frequently require multiple blood transfusions; however, there is a paucity of data regarding the effect of allogeneic blood transfusion following burn injury in a resource-limited setting with a high anemia prevalence at baseline. This study aimed to determine the effect of blood transfusion on burn mortality.
methodsWe performed a retrospective review of patients presenting with burns between 2011 and 2019, using prospectively collected burn registry data from Kamuzu Central Hospital (KCH). We performed multivariate logistic regression modeling to identify predictors of mortality, and we considered potential confounders.
resultsA total of 2359 patients were included. Mean age was 10 ± 14 with a male preponderance (58 %). The mean percent total body surface area burned (%TBSA) was 17.52 ± 14.46. 60 % of burns were caused by scald injuries and 37 % by flame. Below 40 % TBSA, our model predicted a higher probability of mortality for those transfused. However, above 40 % TBSA, the predicted probability of mortality is decreased for those transfused.
conclusionsAllogeneic blood transfusion confers 1.23 (p < 0.03) times higher odds of mortality in burn patients. Mortality risk increased with age and units transfused. This study highlights the need for proper guidelines and protocols for allogeneic blood transfusion in burn patients. A more restrictive blood transfusion strategy may be more appropriate in a resource-limited setting.
