Paris 0-Is lesions were not classified as LST; size is given as mean ± standard deviation.LST-G, laterally spreading tumor granular type; LST-NG, laterally spreading tumor non-granular type; SSA, sessile serrated adenoma; LG-IEN, low-grade intraepithelial neoplasia; HG-IEN, high-grade intraepithelial neoplasia.
