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
backgroundThis study aimed to identify perioperative determinants of prolonged intensive care unit (ICU) stay in a consecutive cohort of pediatric liver transplant recipients, with emphasis on intraoperative hemodynamic and metabolic variables.
methodsThis retrospective, single-center cohort study included 112 consecutive pediatric patients who underwent orthotopic liver transplantation (LT). The primary outcome was ICU length of stay ≥7 days. A multivariable binary logistic regression model was constructed using preoperative and intraoperative variables exclusively, following formal multicollinearity assessment with cluster-based variable selection. Discriminative performance was assessed by receiver operating characteristic analysis with bootstrap-derived CIs.
resultsThirty-two patients (28.6%) experienced prolonged ICU stay. In a model limited by a low events-pervariable ratio (EPV 4.0), 2 variables were associated with prolonged ICU stay: higher graft-to-recipient weight ratio (GRWR; odds ratio [OR] = 1.840, 95% CI: 1.087-3.114; P = .023) and lower preoperative hemoglobin (OR = 0.715, 95% CI 0.521-0.981; P = .038). Peak intraoperative lactate demonstrated moderate standalone discriminative performance (area under the curve 0.745; optimal threshold 6.0 mmol/L, sensitivity 59.4%, specificity 88.7%), without retaining significance in the multivariable model owing to collinearity. Prolonged ICU stay was associated with significantly higher rates of reintubation (40.6% vs. 9.0%; P < .001) and 30-day mortality (31.2% vs. 8.9%; P = .007).
conclusionProlonged ICU stay in pediatric LT was associated with higher GRWR and lower preoperative hemoglobin. Peak intraoperative lactate showed moderate discriminative performance and a strong continuous association with ICU duration. These findings highlight perioperative correlates of ICU utilization that may inform risk stratification and warrant prospective evaluation. Cite this article as: Şahin T, Kavaklı AS, Aydin A, et al.
