Predictors of early extubation after pediatric liver transplantation: a single-center retrospective cohort study.
Observational study in BMC anesthesiology, 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
backgroundLiver transplantation is a cornerstone therapy for pediatric end-stage liver disease. While Enhanced Recovery After Surgery (ERAS) protocols, including early extubation, are well-established in adult liver transplantation, their application in children is more cautious due to unique challenges like malnutrition and poor postoperative cooperation. This study aimed to identify predictors of successful early extubation (within 3 h postoperatively) in pediatric liver transplant recipients.
methodsThis was a single-center retrospective cohort study. We analyzed data from 256 patients under 18 years who underwent liver transplantation between September 2019 and November 2022. Patients were divided into Early Extubation (EE, ≤ 3 h) and Non-Early Extubation (Non-EE, > 3 h) groups. Univariate and multivariate logistic regression analyses were performed to identify factors associated with EE. The efficacy of relevant parameters in predicting early extubation was evaluated using receiver operating characteristic (ROC) curve analysis.
resultsOf the 256 patients, 155 (61%) were successfully extubated early. Multivariate analysis identified the following independent predictors: favorable factors were higher preoperative albumin (ALB) level (adjusted OR 1.167, p = 0.008) and greater intraoperative urine output (adjusted OR 4.686, p < 0.001); unfavorable factors were higher preoperative white blood cell (WBC) count (adjusted OR 0.806, p = 0.038), higher end-of-surgery serum lactate level (adjusted OR 0.548, p < 0.001), presence of a concurrent respiratory tract infection (adjusted OR 0.307, p = 0.021), and receiving a donation after circulatory death (DCD) graft (adjusted OR 0.260, p = 0.030). ROC curve analysis identified optimal cutoff values for predicting early extubation: total urine output showed strong discriminative ability (AUC 0.898, 95% CI 0.859-0.938, sensitivity 79.4%, specificity 88.1%); EOS serum lactate showed moderate discriminative ability (AUC 0.725, 95% CI 0.659-0.791, sensitivity 49.5%, specificity 91.0%); pre-op ALB and pre-op WBC showed modest discriminative ability (AUC 0.663 and 0.623, respectively). Optimal cutoff values were: pre-op ALB ≥ 36.15 g/L, pre-op WBC ≤ 11.82 × 10⁹/L, urine output ≥ 3.05 mL/kg/h, and EOS lactate ≤ 3.55 mmol/L.The EE group had a significantly shorter median ICU stay (3 vs. 3.5 days, p = 0.002), with no significant difference in 30-day complication rates or total hospital stay.
conclusionsPreoperative physiological reserve and infection status (reflected by ALB as a composite marker of hepatic synthetic function and nutritional status, WBC, and respiratory infection), intraoperative organ perfusion and metabolic status (reflected by urine output and lactate level), and graft quality (DCD grafts) are key independent predictors of early extubation, potentially shortening ICU stay and supporting the implementation of ERAS protocols in this population.
