Fig. 4From: Identification and potential mechanisms of a 4-lncRNA signature that predicts prognosis in patients with laryngeal cancerValidation of the 4-lncRNA signature. The area under the ROC was 0.822 in the training set, 0.741 in the test set, and 0.773 in the entire set. There were significant differences in OS between the high- and low-risk groups in all three sets. The results show that the 4-lncRNA signature performed well in predicting the prognosis of laryngeal cancer. a Training set, b Test set, c Entire setBack to article page
