  1. Plaque assessment was conducted using binary (recall) and ternary (Cohen’s kappa) classifications. Adhesion assessment was conducted using binary classification for both recall and Cohen’s kappa. Results for adhesions between the left ovary–right ovary, and uerus–bladder could not be calculated due to the lack of positive samples within the images used in the preliminary clinical utility. Parentheses indicate 95% confidence intervals.
