Correlation of ITGA7 and CD44 with DFS and OS in NSCLC patients. Comparison of DFS (A) and OS (B) between ITGA7 high expression and CD44 high expression group, ITGA7 high expression and CD44 low expression group, ITGA7 low expression and CD44 high expression group as well as ITGA7 low expression and CD44 low expression group. Comparison of DFS (C) and OS (D) between ITGA7 high expression and CD44 high expression group with other patients. The survivals for NSCLC patients were exhibited by Kaplan-Meier curve and the comparison of survival between groups were performed by log-rank test. The factors effecting DFS and OS were examined by univariate and multivariate Cox’s proportional hazards regression model analyses. P<0.05 was considered significant. DFS, disease-free survival; OS, overall survival; ITGA7, integrin-α7; HR, hazard ratio; NSCLC, non-small cell lung cancer.
