Prediction of trauma-induced coagulopathy in early polytrauma: a prospective cohort study.
Article in Frontiers in cardiovascular medicine, 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
Background: Traumatic induced coagulopathy (TIC) is a key factor affecting the prognosis of patients with polytrauma. Early identification of patients at high risk for TIC and timely initiation of damage-control interventions are crucial. This study aims to develop and validate a predictive model for individualized estimation of TIC risk based on clinical characteristics and routine laboratory indicators. Methods: This prospective cohort study included 183 adult patients, aged 18 to 85 years, with confirmed multiple injuries who presented to the emergency department of our hospital between July 1, 2023, and December 31, 2024. Patients were divided into a TIC group ( Results: Four core predictors were ultimately identified: emergency surgery, pH value, red blood cell count (RBC), and Injury Severity Score (ISS).The model demonstrated good discriminative ability (AUC = 0.903, 95% CI: 0.858-0.948).The optimal cut-off value determined by the Youden index was 0.651, with a sensitivity of 81.3% and a specificity of 86.7%.The calibration curve showed high agreement between predicted and observed risks. Decision curve analysis further indicated that the model provided favorable clinical net benefit across a wide range of threshold probabilities. Conclusion: The predictive model developed in this study showed promising ability to estimate individualized TIC risk in patients with polytrauma and may serve as an effective tool to optimize the allocation of medical resources and facilitate early diagnosis and intervention for traumatic coagulopathy.
