Fig. 4From: Effect of machine learning methods on predicting NSCLC overall survival time based on Radiomics analysisExamples of the Kaplan-Meier evaluations. All the NSCLC patients on each validation fold were stratified into low- and high- risk groups based on the cut-off values determined by the corresponding training fold. Here, (a), (b) and (c) presented the Kaplan-Meier curve of the three CV validation folds, respectivelyBack to article page
