Short-term mortality prediction in children with gastrointestinal congenital anomalies using a random forest classifier.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe aim to develop a predictive model to identify children with gastrointestinal congenital malformations at high risk of 30-day mortality following intervention or hospital admission.
methodsThe data used for our analysis was collected as part of the Global PaedSurg research collaboration, and includes 3849 patients from 74 countries. Data preprocessing, missing data imputation, oversampling of the non-survivor class, and random undersampling of the survivor class were performed prior to training a random forest classifier for mortality prediction.
resultsThe overall 30-day mortality in our model dataset is 19.5%. The model displays an overall accuracy of 88.84% (CI: 86.79%, 90.66%), with strong precision (84.13%, CI: 78.4%, 88.8%) and sensitivity (89.98%, CI: 87.8%, 91.9%) in identifying non-survivors. The area under the curve (AUC) is 0.941 (CI: 0.924, 0.957) for subjects in the non-survival class. The most important features in the classifier are the diagnosis of a complication, the duration of postoperative antibiotic treatment, the need for parenteral nutrition or ventilation, the American Society of Anesthesiologists (ASA) score, weight upon admission, and the use of a surgical safety checklist.
conclusionsRandom forest classifier is a viable option for short-term mortality prediction for children with gastrointestinal congenital malformations. IMPACT: To our knowledge, this is the first global study to apply machine learning for mortality prediction in children with gastrointestinal malformations, using data from 3849 patients across 74 countries. The random forest model achieves 88.84% (CI: 86.79%, 90.66%) accuracy, with strong precision (84.13%, CI: 78.4%, 88.8%) and sensitivity (89.98%, CI: 87.8%, 91.9%) in identifying at-risk patients. Key predictors include clinical factors (diagnosis of complications, American Society of Anaesthesiologists score, weight on admission, duration of post-operative antibiotic treatment), procedural elements (surgical checklist), and socio-demographic variables (continent, income level).
