An interpretable machine learning model for predicting febrile seizures following enterovirus infection in children.
Article in Annals of medicine, 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
objectiveThis study aims to develop an interpretable machine learning model for predicting the risk of FS in children with enterovirus (EV) infections and to implement it for clinical application.
methodsThis retrospective study included 446 hospitalized children with EV infection (144 FS, 302 non‑FS). LASSO regression and BORUTA algorithm selected 15 key predictors from 53 clinical variables. Six models (logistic regression, KNN, Naive Bayes, MLP, random forest, XGBoost) were constructed and evaluated using AUC, sensitivity, specificity, F1 score, and decision curve analysis. SHAP values provided interpretability, and a Shiny web‑based calculator was developed.
resultsThe XGBoost model demonstrated the best predictive performance: the training set AUC reached 0.972 (95% CI: 0.958-0.987), with sensitivity of 0.892 and specificity of 0.905. The internal validation set achieved an AUC of 0.842 (95% CI: 0.757-0.926). DCA confirmed its strong clinical applicability. SHAP analysis identified key features contributing to the model: fever duration, disease course, immunoglobulin M, neutrophil count, fibrinogen, CD8+ T-cell percentage, aspartate aminotransferase, CD3+ T-cell percentage, procalcitonin, presence of hand-foot herpes lesions, CD19+ B-cell percentage, erythrocyte sedimentation rate, lymphocyte count, serum ferritin level, and alanine aminotransferase. The 'Shiny' calculator facilitates personalized risk assessment.
conclusionThe XGBoost predictive model developed in this study demonstrated both high accuracy and clinical interpretability. The associated web-based calculator offers a new tool for risk stratification and management of FS in children with EV infections.
