This multicenter retrospective study develops and validates an interpretable machine-learning–based prognostic model using routinely available clinical features. Model training and internal validation draw on 292 patients, while external validation uses 104 patients from a separate center. Feature selection is performed with Boruta, performance is evaluated by AUC and related metrics, and clinical value is assessed with decision curve analysis, with interpretability supported by SHAP.","TYPE Original Research PUBLISHED 19 March 2025  \nDOI 10. 3389/fmicb.2025.1557922  \nOPEN ACCESS  \nEDITED BY  \nPei-Hui Wang,  \nShandong University, China  \nREVIEWED BY  \nYuanchia Chu,  \nTaipei Veterans General Hospital, Taiwan Mehmet Huyut,  \nErzincan University, Türkiye Fida Hussain,  \nIqra University, Pakistan  \n*CORRESPONDENCE  \nYi-Shan Zheng  \n [284159264@qq.com](284159264@qq.com)  \n†These authors have contributed equally to this work and share first authorship  \nRECEIVED 09 January 2025  \nACCEPTED 05 March 2025  \nPUBLISHED 19 March 2025  \nCITATION  \nXu J-S, Yang K, Quan B, Xie J and Zheng Y-S (2025) A multicenter study on developing a prognostic model for severe fever with thrombocytopenia syndrome using machine learning.

Accurate prognostic assessment is crucial for developing individualized prevention and treatment strategies. However, machine learning prognostic models for SFTS are rare and need further improvement and clinical validation.  \nObjective: This study aims to develop and validate an interpretable prognostic model based on machine learning (ML) methods to enhance the understanding of SFTS progression.  \nMethods: This multicenter retrospective study analyzed patient data from two provinces in China. The derivation cohort included 292 patients treated at The Second Hospital of Nanjing from January 2022 to December 2023, with a 7:3 split for model training and internal validation. The external validation cohort consisted of 104 patients from The First A􀀈liated Hospital of Wannan Medical College during the same period. Twenty-four commonly available clinical features were selected, and the Boruta algorithm identified 12 candidate predictors, ranked by Z-scores, which were progressively incorporated into 10 machine learning models to develop prognostic models. Model performance was assessed using the area under the receiver-operating-characteristic curve (AUC), accuracy, recall, and F1 score. The clinical utility of the best-performing model was evaluated through decision curve analysis (DCA) based on net benefit. Robustness was tested with 10-fold cross-validation, and feature importance was explained using SHapley Additive exPlanation (SHAP) both globally and locally.  \nResults: Among the 10 machine learning models, the XGBoost model demonstrated the best overall discriminatory ability. Considering both AUC index and feature simplicity, a final interpretable XGBoost model with 7 key features was constructed. The model showed high predictive accuracy for patient outcomes in both internal (AUC = 0.911, 95% CI: 0 .842–0.967) and external validations (AUC = 0.891, 95% CI: 0 .786–0.977) .
