Morphomics in esophageal cancer: Validation and association with muscular and cardiorespiratory fitness

Figure 3 Receiver operator curve analysis for predicting patients with low cardiorespiratory fitness from the morphomics. The area under the receiver operator curve curves (AUC) was 0.840, and optimism-corrected AUC was 0.778 under the setting of 1000 bootstrap resamples internal validation (95% confidence interval 0.628-0.0.882, P < 0.001). AUC: Area under the receiver operator curve; ROC: Receiver operator curve.
