Nine-long non-coding ribonucleic acid signature can improve the survival prediction of colorectal cancer

Figure 2 Validation of the nine-long noncoding ribonucleic acid signature in the testing set and entire set. A: Kaplan-Meier overall survival (OS) analysis in the testing set between patients in the high-risk group and low-risk group; B: Kaplan-Meier OS analysis in the entire set between patients in the high-risk group and low-risk group; C: Distribution of risk score, OS and long noncoding ribonucleic acid expression for the patients in the testing set; D: Distribution of risk score, OS and long non-coding ribonucleic acid expression for patients in the entire set. Columns represent patients.
