The flowchart of the study. Training staff interviewed eligible participants via a uniform and laptop-based questionnaire to collect information on their exposure to risk factors (psychological information included) (N = 15,981). An esophageal endoscopy examination would be performed after the questionnaire (N = 15,981). If esophageal endoscopy results were suspicious (N = 6061), a pathological biopsy would be further conducted (N = 6061). Screeners were diagnosed as health (N = 987), esophagitis (N = 4048), low-grade intraepithelial neoplasia (LGIN) (N = 769), high-grade intraepithelial neoplasia (HGIN) (N = 157), esophageal cancer (EC) (N = 55), and unclear (N = 45)
