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
Objective: Traumatic hemorrhage is the predominant preventable cause of mortality in severe trauma cases. Timely and efficacious hemostatic resuscitation is crucial for the management of severe traumatic hemorrhages. This study aimed to evaluate the association between implementation of viscoelastic hemostatic assay (VHA)/TEG-guided hemostatic resuscitation and clinical outcomes among transfused traumatic hemorrhage patients who survived at least 24 h after emergency department arrival in China. Methods: We conducted a retrospective, single-center before-after cohort study of trauma patients admitted to the emergency department of a tertiary trauma center from January 2012 to December 2021. Patients admitted from 2012 to 2016 were managed using a conventional coagulation assay (CCA)-guided strategy, whereas patients admitted from 2017 to 2021 were managed using a VHA/TEG-guided strategy. Because the analysis required complete 24-h coagulation and transfusion-response data, the primary cohort was defined as transfused traumatic hemorrhage patients who survived at least 24 h after emergency department arrival. Propensity score matching was used to reduce baseline imbalance. The primary outcome was post-24-h in-hospital mortality. Results: A total of 154 patients who survived at least 24 h were included after propensity score matching, with 77 patients in each group. Post-24-h in-hospital death occurred in 21 of 77 patients in the CCA-guided group and 9 of 77 patients in the VHA-guided group. Kaplan-Meier analysis showed improved post-24-h in-hospital survival in the VHA-guided group (log-rank Conclusion: Among transfused traumatic hemorrhage patients who survived at least 24 h, VHA-guided hemostatic resuscitation was associated with improved post-24-h in-hospital survival, reduced plasma exposure, greater fibrinogen-directed replacement, and improved PT correction. This study cannot determine whether VHA-guided resuscitation improves survival during the initial 24 h, when early hemorrhagic mortality is highest. Because of the retrospective before-after design, survivorship bias, and residual confounding, these findings should be interpreted as hypothesis-generating.
