Survival curves according to GLI1 and GLI3 mRNA expression in stage III-IV lung adenocarcinoma patients. Kaplan-Meier analysis was performed on the basis of GLI1 and GLI3 mRNA expression in patients with stage III-IV lung adenocarcinoma. P values were estimated by log-rank test. Higher GLI1 and GLI3 mRNA expression also correlated with unfavorable patient survival. (a) Overall survival; (b) Disease-free survival. Ticks: censored cases; Bold values: statistically significant.
