*

The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).

**

RB > LP indicates that robotics had a more favourable profile for the specific outcome; RB < LP indicates robotics had a less favourable profile for the specific outcome.

CI: Confidence interval; OR: Odds ratio; RB: Robotics; LP: Laparoscopy.

GRADE Working Group grades of evidence

High quality: Further research is very unlikely to change our confidence in the estimate of effect.

Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.

Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

Very low quality: We are very uncertain about the estimate.

1

Odds ratios cover <1 and >1, with previous surgical skill likely contributing.

2

Mean differences cover negative and positive values, with previous surgical skill likely contributing.
