FA2H and esophageal squamous cell carcinoma: Kaplan–Meier survival analysis further demonstrated that higher FA2H expression indicated unfavorable overall survival (OS) (n = 306, P = 0.0125; Fig. 2f and Supplementary Fig. 3i) and disease-free survival (DFS) (n = 306, P = 0.0209; Fig. 2g) in patients with ESCC.
