1 · What the graph read from it

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.

2 · The registry

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

objectivesTo explore the risk factors for concomitant anxiety in patients with malignant gastrointestinal tumors based on machine learning algorithms.

methodsA total of 280 patients with malignant gastrointestinal tumors admitted to the First Affiliated Hospital of Bengbu Medical University from November, 2022 to April, 2023 were enrolled, and the collected data were re-analyzed between November ,2024 and April, 2025. According to Hospital Anxiety and Depression Scale (HADS-A) anxiety scores, the patients were divided into anxiety group (HADS-A score≥8) and non-anxiety group (<8). Six machine learning algorithms including Logistic Regression, Decision Tree, Random Forest, K-Nearest Neighbors, Support Vector Machine and Light Gradient Boosting Machine were used to predict anxiety. The performance of each model was assessed, and the factors affecting anxiety in these patients were identified by feature importance ranking and SHAP analysis by the optimal model.

resultsAmong the 6 machine learning algorithms for predicting anxiety in patients with malignant gastrointestinal tumors, the Random Forest model showed the best performance with an accuracy of 0.73, precision of 0.48, recall of 0.86, specificity of 0.69, F1-Score of 0.62, and the area under the ROC curve (AUC) of 0.85, and was more accurate for identifying and classifying anxiety status in the target patients. According to the feature importance ranking by the optimal model, the top 10 key factors affecting anxiety in these patients were total cholesterol (0.0406), gender (0.0224), albumin (0.0157), platelet count (0.0152), white blood cell count (0.0121), retinol-binding protein (0.0116), total protein (0.0115), body mass index (0.0098), C-reactive protein (0.0096), and platelet distribution width (0.0095).

conclusionsThe Random Forest model has good performance for predicting anxiety and screening key factors affecting anxiety in patients with malignant gastrointestinal tumors to facilitate its early identification and targeted intervention.
