From: A long non-coding RNA signature to improve prognosis prediction of gastric cancer
Kaplan-Meier estimates of the disease free survival (DFS) of GEO patients using the 24-lncRNA signature, stratified by postoperative chemotherapy. Entire GSE62254 set (N = 299) were first stratified by postoperative chemotherapy (with or without postoperative chemotherapy). Kaplan-Meier plots were then used to visualize the survival probabilities for the high-risk versus low-risk group of patients determined on the basis of the median risk score from the GSE62254 set patients within each postoperative chemotherapy stratum. a Kaplan-Meier curves for the entire GSE62254 set patients (N = 299); (b) Kaplan-Meier curves for patients with postoperative chemotherapy (N = 80); (c) Kaplan-Meier curves for patients without postoperative chemotherapy (N = 219). The tick marks on the Kaplan-Meier curves represent the censored subjects. The differences between the two curves were determined by the two-sided log-rank test
