FS, frozen section; RV, radiomics combining with volume; CSRV, radiomics combing with clinical, semantic, and volume; FSV, frozen section combining with volume; FSRV, frozen section combining with radiomics and volume; CSFSRV, radiomics combining with clinical, semantic, volume, and frozen section; AUC, the area under the curve; CI, confidence interval. *p < 0.05; P1 = p values between radiomics and other models; P2 = p values between CSRV and other models; P3 = p values between FSRV and other models. p values calculated using roc test by Delong method
