Relationship between eCura scores and CR status.
Each symbol represents 1 patient. The long and short vertical bars represent the mean and mean ± standard deviation, respectively. According to the eCura risk scoring system, CR positivity rates were 0% (0/12), 17% (4/23), and 50% (5/10) in the low-risk group, intermediate-risk group, and high-risk group, respectively.

Relationship between histological type and CR status in the 46 cases with en bloc ESD.
Fig 2 shows the relationship between the main histological types and CR status in the 46 cases with en bloc ESD. One case was excluded due to possible inaccuracy of histological diagnosis because of piecemeal ESD. Positive CR is recognized in 8 patients, which included 3 cases of LNM, 4 cases of local CR, and 1 case of both local CR and LNM. Note that CR was positive in only the cases of moderately differentiated type (tub2) in the differentiated group.
