The modelling process included the folowing: (1) clinical model construction through logistic regression analysis of risk factors; (2) radiomics model development by comparing 6 machine learning classifiers; and (3) integration of optimal clinical and radiomic features into a combined model. Model performance was assessed using the area under the curve (AUC), calibration curves, and decision curve analysis (DCA) . A nomogram was constructed for clinical implementation. Results: Two clinical risk factors (BMI and CA153) were identified as independent predictors of differentiated HCC. The clinical model showed moderate performance (AUC: training = 0.705, validation = 0.658) . The radiomics model demonstrated improved prediction capability (AUC: training = 0.840, validation = 0.716) . The combined model achieved the best performance in differentiating HCC pathological grades (AUC: training = 0.878, validation = 0.747) .  \nConclusions: The integration of CT radiomics features with clinical parameters through machine learning provides a promising non-invasive approach for predicting HCC pathological differentiation. This combined model could serve as a valuable tool for preoperative treatment planning.  \nKeywords: hepatocellular carcinoma, computed tomography, radiomics, machine learning, pathological grading.  \nIntroduction  \nThe incidence of hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, continues to rise globally, making it a significant cause of cancerrelated mortality [1,2] . Accurate preoperative assessment of HCC pathological differentiation is crucial because it  \ndirectly influences treatment planning and patient outcomes [3,4] . Evidence suggests that patients with well to moderately differentiated HCC demonstrate superior overall survival rates and lower recurrence risks compared  \nto those with poorly differentiated tumours [5,6] .  \nAlthough postoperative pathological examination remains the gold standard for determining HCC differentia-  \nCorrespondence address:  \nProf. Bin Zhong & Jin Li, School of Basic Medical Sciences, Youjiang Medical University for Nationalities, China, e-mails: [zb@ymun.edu.cn](zb@ymun.edu.cn); [jin_lijin@cmu.ac.th](jin_lijin@cmu.ac.th)  \nAuthors’ contribution:  \nA Study design ∙ B Data collection ∙ C Statistical analysis ∙ D Data interpretation ∙ E Manuscript preparation ∙ F Literature search ∙ G Funds collection  \ne140  \nThis is an Open Access journal, all articles are distributed under the terms of the Creative Commons Attribution-Noncomm","cbCaifpa7QUlKHfX","https://ap.wps.com/l/cbCaifpa7QUlKHfX","pdf",1597848,1,11,"English","en",105,"# Abstract\n## Purpose\n## Material and methods\n## Results\n## Conclusions\n# Introduction\n## Clinical need for differentiation assessment\n## Limits of conventional imaging\n## Role of radiomics and study gap\n## Study objective","[{\"question\":\"What does the study evaluate in hepatocellular carcinoma (HCC)?\",\"answer\":\"The study evaluates how well a combined clinical-radiomics model predicts HCC pathological differentiation using multiple machine learning approaches.\"},{\"question\":\"How were the prediction models constructed and validated?\",\"answer\":\"Patients with preoperative CT were retrospectively enrolled (training n=156, validation n=40).
