Machine learning-based radiomics score improves prognostic prediction accuracy of stage II/III gastric cancer: A multi-cohort study

Figure 5 The area under the curve of skeletal muscle index, skeletal muscle density, and overall survival-associated computed tomography image radiomics score for overall survival prediction. A: Discovery cohort; B: The Cancer Imaging Archive cohort. AUC: Area under the curve; TCIA: The Cancer Imaging Archive; OACRS: Overall survival-associated computed tomography image radiomics score; SMI: Skeletal muscle index; SMD: Skeletal muscle density.
