Thromboelastographic description of intraoperative coagulopathy in patients undergoing liver transplant surgery: A single-center observational study.
Article in World journal of transplantation, 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
backgroundPatients undergoing liver transplantation often develop multiple hemostatic abnormalities requiring dynamic transfusion and antifibrinolytic support; however, how hemostatic status changes over time during liver transplant surgery is not well defined, limiting clinicians' ability to anticipate and manage hemostatic instability.
aimTo describe the distribution of intraoperative coagulation abnormalities across the surgical phases of liver transplantation.
methodsWe conducted an observational study of adult patients who underwent liver transplantation at Henry Ford Health between January 2017 to April 2022. Intraoperative coagulation data from conventional coagulation tests and 2 thromboelastography (TEG) platforms (TEG 5000 and TEG 6s) were collected. Data were stratified across 4 surgical phases: Pre-anhepatic, anhepatic, post-reperfusion, and end-of-surgery.
resultsOf 364 liver transplant recipients, coagulation abnormalities occurred during all surgical phases, with the highest frequency in the anhepatic and post-reperfusion phases. Platelet dysfunction was the most common abnormality, peaking during post-reperfusion, while hyperfibrinolysis was less frequent and resolved in most patients by the end of surgery. TEG 5000 and TEG 6s showed slightly different result patterns for several parameters, particularly for clot initiation time and fibrinogen activity.
conclusionTEG was more informative than conventional tests, showing peak coagulation derangements during anhepatic and post-reperfusion phases of liver transplantation, likely driven by platelet dysfunction and warranting increased vigilance for coagulopathy.
