Comparing Rotational Thromboelastometry and Standard Coagulation Assays for Predicting Intraoperative Bleeding in Pediatric Liver Transplantation.

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
backgroundUtility of preoperative rotational thromboelastometry (ROTEM) over standard coagulation assays (SCAs) in predicting intraoperative bleeding during orthotopic liver transplantation (OLT) in children with liver failure (LF) remains unclear.
methodsIn this single-center retrospective cohort of pediatric OLT recipients, we compared the predictive values of preoperative ROTEM parameters (intrinsic pathway (INTEM) maximum clot firmness (MCF), extrinsic pathway (EXTEM) clotting time (CT), INTEM CT, and fibrinogen-based (FIBTEM) MCF) and the corresponding SCAs (platelet count, international normalized ratio (INR), activated partial thromboplastin time (aPTT), and fibrinogen level, respectively) for significant intraoperative bleeding (blood loss of > 22 mL/kg; i.e., ≥ 85th percentile for the cohort).
resultsSeventy-two children (44 with chronic liver disease, 15 with acute liver failure, and 13 with acute-on-chronic liver failure), with a median age of 39 (IQR 13-159) months, were included. Twelve children (17%) had significant intraoperative bleeding. Most ROTEM parameters and the corresponding SCAs strongly correlated, except for EXTEM CT and INR (Rho of 0.501 and confidence interval (CI) of 0.298-0.660). A combination of SCA parameters performed better than the combination of corresponding ROTEM parameters (area under the curve of 0.862 vs. 0.760; p = 0.029) in predicting significant intraoperative bleeding. Among coagulation parameters, only platelet count was associated with significant intraoperative bleeding (adjusted Odds Ratio of 1.02, CI of 1.00-1.04; p = 0.009).
conclusionsROTEM parameters and SCAs have comparable predictive value for significant intraoperative bleeding in children with LF requiring OLT. Further investigation is required to assess how ROTEM can be effectively used in managing coagulopathy in pediatric LF.
