Overview of radiomics analysis in this study. The volume of interest (VOI) was formed after region of interest (ROI) outlining on the arterial phase of CT enhancement. Features were extracted from the VOI and selected using least absolute shrinkage and selection operator (LASSO) regression. A combined radscore-clinical model was developed to predict overall survival (OS) in patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE), and a Kaplan–Meier (K-M) stratification analysis of risk factors for predicting OS was performed.
