Data on representative patient characteristics obtained from medical records are summarized in this table. For each item, we calculated the average and standard deviation, minimal and maximal value, and count data from medical records. “Polyp size” refers to the maximum length of the target polyp measured by transvaginal ultrasonography before hospitalization in an outpatient setting. In the calculation of polyp size, 25 cases described as having a “small polyp” without specific figures in the medical records were excluded.
