The Kaplan-Meier plot of TCGA data base (Figure 1F) and our clinical samples (Figure 1G) both demonstrated that patients with low CHRDL1 expression exhibited poorer survival than those with high CHRDL1 expression, suggesting that CHRDL1 expression might act as a prognostic factor in patients with gastric cancer. Here, CHRDL1 is linked to gastric cancer.
