Figure 1 Flow diagram. The flow diagram shows the study selection process. 1One study was divided into Western and Eastern parts for our quantitative analysis (thus counting as two studies). It was however only counted as a single study when assessed for eligibility; 2Missing/incomplete data regarding our primary outcome (curative, en bloc, R0 resection); 3Non-ESD study, hybrid ESD technique, ESD with snare; 4Submucosal lesions, pharyngeal lesions; 5Case-control, case report, questionnaire.
