IQR = interquartile range, TAH = total abdominal hysterectomy, BSO = bilateral salpingo-oophorectomy
Data are median (interquartile range), or n (%) unless otherwise specified. Missing values were excluded from the denominator of the percentages.
Analyses were performed by Fisher exact test (if cell count was less than 5) or Chi-square test for categorical variables; and independent t-tests for continuous variables.
*
Missing data for staples group only, n=81, except for incision closure time, n=78.
†
Both groups have missing data, n=79 for staples group and n=72 for suture group.
