Overall survival of gastric cancer patients with positive or negative DDR1 expression. a Kaplan-Meier survival curves showed that positive DDR1 expression was associated with a lower overall survival rate in all patients enrolled in the study (P = 0.015 by log-rank test). b In the non-adjuvant chemotherapy subgroup, the overall survival rate of patients with positive and negative DDR1 expression was comparable (P = 0.933 by log-rank test). c In patients receiving adjuvant chemotherapy, positive DDR1 expression was significantly correlated with a poor overall survival rate (P = 0.013 by log-rank test)
