Minimally invasive include laparoscopic and robotic surgeries. Both age (yr) and the length of stay (d) are given as the median of the means or medians reported in the individual studies. Both the proportion of women and the proportion of malignant disease are given as the median of the proportions reported in the individual studies. Not all procedures are included in this table (Supplemental Digital Content Appendix, pages 137–145, 181–189, and 226–238, complete characteristics for all procedures).
NA indicates not applicable; NR, not reported.
