Tranexamic Acid for Acute Bleeding in Severely Traumatized Patients: Mortality, Neurological Outcomes, and Thromboembolic Risk.
Review in Deutsches Arzteblatt international, 2026. 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
backgroundThe optimal use of tranexamic acid (TXA) in trauma care is a matter of intense discussion, particularly with respect to its indications, dosage, temporal window, and thromboembolic adverse effects.
methodsThis review is based on publications retrieved by a selective literature search on the indications, effects, mechanism of action, and side effects of TXA (January 2022 to December 2025). Three randomized, controlled trials (RCTs), three observational studies, eight secondary analyses, and 16 meta-analyses were evaluated.
resultsTXA administration lowers the mortality of severely traumatized patients (e.g., with a relative risk [RR] of 0.73 [0.56;0.96]). The currently available evidence is inconsistent, and many of the effects found in published studies lie within the range of random fluctuation. The reduction of mortality depends on TXA administration at the earliest possible time in the first 90 minutes after trauma (this temporal window is more important than the question of pre- vs. in-hospital administration), as well as on the nature of the injury, particularly in patients with hemorrhagic shock. Among patients with isolated traumatic brain injury, no consistent effect on mortality has been shown, but there may be an effect on the progression of intracranial bleeding. Multiple studies point to a thromboembolic risk, which is dose-dependent, with a marked rise at 4 g (hazard ratio [HR] 5.33, 95% confidence interval [1.94;14.63]). In patients without shock, the reported absolute risk difference for mortality ranges from -5% to +5%, and that for thromboembolic adverse events from -0.2% to +4%.
conclusionFor trauma patients with life-threatening hemorrhage, especially those in hemorrhagic shock, it is recommended that TXA be given as early as possible (before arrival in the hospital) in a single dose of 1-2 g (15-30 mg/kg body weight [BW]). When this is done, the benefit appears to be greater than the thromboembolic risk.
