Does TXA reduce total volume of 24-hour blood products transfused in post-traumatic hemorrhage in a resource-constrained setting:Secondary analysis of a prospective cohort trauma study in South Africa.
Article in International journal of emergency medicine, 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
backgroundLow- and middle-income countries bear a disproportionately large share of the global burden of trauma, with hemorrhage as a leading cause of preventable mortality. Tranexamic acid has been shown to reduce mortality in trauma, but no studies have investigated tranexamic acid's effect on blood product consumption in resource-constrained settings.
methodsA prospective secondary analysis was performed from data collected from 'The Epidemiology and Outcomes of Prolonged Trauma Care (EpiC)' study, a multicenter observational study of major trauma patients within the Western Cape of South Africa. Adult trauma patients with major hemorrhage who arrived at an EpiC study site within 24 h of injury between March 2021 and December 2024 were included. The primary outcome was total blood product administration within 24 h of injury. Treatment groups included patients who received tranexamic acid within 3 h compared to those who did not. Multiple regression with inverse probability weighting was performed to mitigate confounding. Subgroup analyses included patients with penetrating injuries, severe shock, presence of intracranial hemorrhage and patients without head injury who received large-volume blood products.
resultsA total of 1630 patients were included. Median total blood product volume was 760 mL. There was no difference in blood volume between the two groups. There was no significant difference in blood product volumes observed in all subgroup analysis.
conclusionIn a cohort of adult trauma patients with major hemorrhage, there was no difference in total blood volume transfused within the first 24 h between patients who received tranexamic acid compared to those who did not.
