Also worth noting that complications and major complications were apparently lower (20% lower with major complications) with the robots but the study did not get to the hurdle of statistical significance. N.B. for people who have no clue about statistics: failure to achieve statistical significance does not show no effect. In reality this study suggests that there was a useful effect, but did not conclusively prove it. This confusion happens so often in medical papers it is almost a meme. A meme that has killed a lot of people (see e.g. the Vioxx fiasco).
