Development history (n)	Screening intervals (months)
Lugol‐stained mucosa surrounding EMR (3) → mF (3)	9, 13, 48
Lugol‐stained mucosa surrounding EMR (3) → MD (3)	6, 15, 16
Lugol‐stained mucosa surrounding EMR (3) → SD (3)	6, 6, 12
Lugol‐stained mucosa surrounding EMR/MD (1) → intramucosal carcinoma (1)	26
Lugol‐stained mucosa surrounding EMR/Bch (1) → SD (1)	8
