Coagulopathy as a predictor of the effectiveness of tranexamic acid in severe blunt trauma: a multicenter retrospective study.
Article in Thrombosis journal, 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
backgroundTranexamic acid (TXA) reduces mortality in severe trauma cases. However, the relationships between TXA administration and coagulation/fibrinolysis abnormalities are unclear. We performed a retrospective observational study to investigate relationships between mortality and coagulation/fibrinolysis abnormalities of patients on arrival at the emergency department and whether TXA is more effective in patients with severe trauma who have coagulation/fibrinolysis abnormalities than in those who do not.
methodsData was collected from 15 tertiary emergency and critical care centers in Japan. Adult patients with blunt trauma and an Injury Severity Score of ≥ 16 were included in the study. Patients were categorized into two groups: the TXA group received TXA within 3 h of arrival, and the non-TXA group did not.
resultsOverall, 790 patients were included (TXA group, 276; non-TXA group, 514). In cubic spline curves for relationships between mortality and coagulation/fibrinolysis variables on arrival, odds for mortality increased and plateaued with a prothrombin time-international normalized ratio ≥ 1.2; the disseminated intravascular coagulation (DIC) score showed a marked odds increase when > 4 points. Odds increased and plateaued from an activated partial thromboplastin time (APTT) of ≥ 35 s and gradually increased as fibrinogen decreased from 250 mg/dL. Fibrinogen and fibrin degradation products (FDP) and D-dimer exhibited upward-sloping curves. In cubic spline curves for relationships between the effectiveness of TXA administration and coagulation/fibrinolysis variables on arrival, a favorable effect on mortality was observed with TXA administration when fibrinogen was ≤ 200 mg/dL or when the DIC score was ≥ 4 points; FDP, ≥ 50 µg/mL; D-dimer, ≥ 30 µg/mL; or APTT, ≥ 35 s. In each threshold subgroup, interactions between TXA administration and in-hospital mortality were observed.
conclusionsTXA demonstrates increased effectiveness in patients with traumatic coagulation/fibrinolysis abnormalities.
