This study evaluates whether the triglyceride-glucose (TyG) index predicts HCE occurrence and adverse clinical outcomes in critically ill diabetics, and develops a machine-learning risk model. A multicenter retrospective cohort with TyG calculated within 24 hours post-admission analyzes HCE incidence, in-hospital death, and ICU death, using regression, weighting, matching, and SHAP-based variable importance. Elevated TyG is independently associated with higher death risk.","OPEN ACCESS  \nEDITED BY  \nMithun Rudrapal,  \nVignan’s Foundation for Science, Technology and Research, India  \nREVIEWED BY  \nSamiksha Garse,  \nDY Patil Deemed to be University, India Kratika Singh,  \nCentre of Bio-Medical Research (CBMR), India  \n*CORRESPONDENCE  \nRui Zhang  \n [zztg@163.com](zztg@163.com)[ ](zztg@163.com)Jianhua Cheng  \n [cjh19940317@163.com](cjh19940317@163.com)[ ](cjh19940317@163.com)Jian Xu  \n [xujianqdmc@126.com](xujianqdmc@126.com)  \n†These authors have contributed equally to this work  \nRECEIVED 18 June 2025  \nACCEPTED 20 August 2025  \nPUBLISHED 04 September 2025  \nCITATION  \nXie M, Zhang Y, Wu H, Wu Z, Han H, Xie X, Zhang R, Cheng J and Xu J (2025) Correlation of triglyceride-glucose index with the incidence and prognosis of hyperglycemic crises in critically ill patients with diabetes mellitus: a machine-learning-based multicenter retrospective cohort study.  \nFront.

The triglyceride-glucose (TyG) index, an emergent insulin resistance surrogate, lacks rigorous investigation regarding HCE occurrence trajectories and prognostic sequelae among critically ill diabetics. This study aims to evaluate the relationship between the TyG index and HCE incidence/clinical outcomesin critically ill patients with DM and to construct a risk prediction model using machine-learning algorithms.  \nMethods: This multi-center retrospective investigation leveraged clinical repositories from Medical Information Mart for Intensive Care IV (MIMICIV) and eICU Collaborative Research Database (eICU-CRD) . Inclusion criteria encompassed critically ill subjects with diabetes possessing computable TyG indices within 24 h post-admission. The main study endpoints included death occurring during hospitalization and death within the intensive care unit. TyG index-outcome interrelationships underwent interrogation via logistic regression, restricted cubic spline (RCS), correlation, and linear analytical methodologies. Overlap weighting (OW), inverse probability treatment weighting (IPTW), and propensity score matching (PSM) mitigated confounding influences. Stratified examinations occurred per determinant factors. Five machine-learning architectures constructed mortality prognostication frameworks, with SHapley Additive exPlanations (SHAP) delineating pivotal predictors.  \nResults: Among 4,098 critically ill patients with DM, 328 developed HCE. Patients with HCE had significantly higher TyG levels [10 .2 (","cbCaip4wXBqMMhWs","https://ap.wps.com/l/cbCaip4wXBqMMhWs","pdf",3057226,1,14,"English","en",105,"# Background\n# Methods\n# Results\n# Conclusion\n# Keywords","[{\"question\":\"What clinical conditions are included as hyperglycemic crisis events in this study?\",\"answer\":\"Hyperglycemic crisis events include diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS).
