1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundObesity poses significant challenges in colorectal surgery, affecting operative difficulty and postoperative recovery. The choice of minimally invasive approach for this patient population remains a challenge during preoperative planning. This review aims to provide an updated synthesis of studies comparing laparoscopic and robotic approaches for adult patients with obesity undergoing colorectal surgery.

methodsMEDLINE, Embase and CENTRAL were searched up to August 2023. Articles were included if they compared laparoscopic and robotic colorectal surgery outcomes in adults with obesity (BMI ≥30 kg/m

resultsAfter screening 2187 citations, 10 observational studies were included with 3281 patients with obesity undergoing robotic surgery (mean age: 58.1 years, female: 43.9%) and 11 369 patients with obesity undergoing laparoscopic surgery (mean age: 58 years, female: 53.2%). Robotic surgery resulted in longer operative times (MD 46.71 min, 95% CI 33.50-59.92, p < 0.01, I

conclusionThese data suggest that robotic colorectal surgery in patients with obesity may reduce the risk for conversion to laparotomy, but at the expense of increased operative times and with no overt benefits in postoperative outcomes. Further high quality randomized controlled trials assessing the utility of robotic surgery in patients with obesity undergoing colorectal surgery are warranted.
