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
Objective: To develop and validate a predictive model for neonatal gastrointestinal infections using multiple machine learning algorithms. Methods: We conducted a retrospective analysis of 176 neonates diagnosed with nosocomial gastrointestinal infections in NICU between 2020 and 2024, along with a randomly selected control group of 675 neonates without such diagnoses during their NICU stay. The study examined 29 perinatal and NICU treatment-related risk factors potentially associated with neonatal gastrointestinal infections. The dataset was randomly partitioned into training and testing sets. To address class imbalance and enhance minority class identification, we applied SMOTE to the training set.Feature selection used Boruta, Lasso, and Logistic regression, with consensus features from Venn analysis.Subsequently, eight machine learning algorithms were implemented to construct predictive models. Models were evaluated using AUC, F1 score, accuracy, sensitivity, and specificity. Results: The model incorporated nine significant feature variables: gestational age, NE, PLT, central venous catheterization, nasogastric feeding, delivery mode, intrauterine distress, pregnancy-induced hypertension, and probiotic administration. Among the eight machine learning algorithms evaluated, the Neural Network model demonstrated optimal performance - achieving perfect metrics in the training set (AUC=0.895, F1=0.845, Accuracy=0.837, Sensitivity=0.888, Specificity=0.786, Precision=0.806) and robust results in the test set (AUC= 0.876, F1=0.862, Accuracy=0.856, Sensitivity=0.896, Specificity=0.817, Precision=0.830) - thus was selected as the final predictive model. Model interpretability was enhanced through SHAP analysis. Furthermore, a Shiny-based interactive web calculator for neonatal gastrointestinal infection risk prediction was successfully developed based on this model. Conclusion: The model effectively identifies at-risk neonates early, supporting clinical decision-making and timely interventions.
