This cohort study (January 2023\u2013December 2025) included 300 ICU patients receiving early enteral nutrition. Baseline clinical characteristics, intra-abdominal pressure, laboratory indices, and quantitative gut microbial taxa were collected. Candidate predictors were selected using the least absolute shrinkage and selection operator regression, and independent predictors were incorporated into a multivariable logistic regression model, which was presented as a nomogram. Model performance was assessed using discrimination, calibration, and decision curve analyses. The incidence of EENI was 49.00% (147\/300). LASSO selected 16 features: age, analgesic use, serum albumin, glucose, IAP, and the absolute counts of\n                    <jats:italic>Enterococcus, Bacteroides, Escherichia-Shigella, Klebsiella, Bifidobacterium<\/jats:italic>\n                    , and\n                    <jats:italic>Parabacteroides<\/jats:italic>\n                    .

The model achieved an AUC of 0.900 (95% CI: 0.863\u20130.936) in the training set and 0.900 (95% CI: 0.859\u20130.941) in the validation set. Calibration was good (Hosmer-Lemeshow P = 0.425 and P = 0.423, respectively). DCA demonstrated clinical utility across a wide range of risk thresholds. The developed machine learning model, combining IAP and selected genus-level gut microbial markers, demonstrates strong predictive performance and clinical potential for forecasting and managing early enteral nutrition intolerance in ICU patients.\n                  <\/jats:p>","DOI":"10.33073\/pjm-2026-023","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T14:03:54Z","timestamp":1786025034000},"page":"243-257","source":"Crossref","is-referenced-by-count":0,"title":["Machine Learning\u2013Driven Prediction of Early Enteral Nutrition Intolerance in ICU Patients Using Intra-Abdominal Pressure and Selected Gut Microbial Taxa"],"prefix":"10.33073","volume":"75","author":[{"given":"Kaihui","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Critical Care Medicine, Wenzhou Central Hospital , Wenzhou , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuena","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Critical Care Medicine, Wenzhou Central Hospital , Wenzhou , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lishi","family":"Qu","sequence":"additional","affiliation":[{"name":"Department of Neonatology, the 2nd Affiliated Hospital and Yuying Children\u2019s Hospital of Wenzhou Medical University , Wenzhou , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renshu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Critical Care Medicine, Wenzhou Central Hospital , Wenzhou , China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"18083","published-online":{"date-parts":[[2026,6,30]]},"reference":[{"key":"2026081913074027122_j_pjm-2026-023_ref_001","doi-asserted-by":"crossref","unstructured":"Bejarano N, Navarro S, Rebasa P, Garc\u00eda-Esquirol O, Hermoso J. 2013.
