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

Figure 4 Overall survival-associated computed tomography image radiomics score as a biomarker for overall survival. A and B: Survival curves of stage II/III patients in the discovery and the Cancer Imaging Archive (TCIA) cohorts; C: Calculating the optimal cut-off value of the overall survival-associated computed tomography image radiomics score (OACRS); D and E: Survival curves of patients with low and high OACRS in the discovery and TCIA cohorts. TCIA: The Cancer Imaging Archive; OS: Overall survival; OACRS: Overall survival-associated computed tomography image radiomics score.
