Kaplan–Meier curves post-NAC GR, post-NAC Sgk1, and post-NAC NDRG1. a The 5-year overall survival of the patients with esophageal squamous cell carcinoma (ESCC) exhibiting high post-NAC GR was significantly worse than those with low post-NAC GR. b No significant differences in the 5-year disease-free survival (DFS) detected between those exhibiting high and low post-NAC GR in carcinoma tissues. c The 5-year overall survival of those exhibiting high post-NAC Sgk1 was significantly worse than those of low post-NAC status. d The 5-year DFS of those exhibiting high post-NAC Sgk1 was significantly worse than those with low post-NAC Sgk1. e The 5-year overall survival of those exhibiting high post-NAC NDRG1 was significantly worse than those with low post-NAC NDRG1. f The 5-year DFS of those exhibiting high post-NAC NDRG1 was significantly worse than those with low post-NAC NDRG1
