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

purposeThe aim of this study is to clarify the short-term outcomes of robotic sphincter-preserving surgery for rectal cancer in a retrospective study.

methodsThe short-term outcomes of robotic sphincter-preserving surgery (n = 130) were retrospectively compared to open (n = 234) and laparoscopic surgery (n = 318) by a propensity score analysis.

resultsRobotic surgery was performed more frequently for patients with lower rectal cancer (55%) than open (30%, p < 0.0001) or laparoscopic surgery (36%, p < 0.0001). None of the robotic surgery cases were converted to open surgery. After propensity score matching, robotic surgery was found to be associated with a longer operation time (342 vs. 230 min, p < 0.0001) and less blood loss (7 vs. 420 mL, p < 0.0001) than open surgery. The overall complication rate of robotic surgery was lower than that of open surgery (13 vs. 28%, p = 0.032). Robotic surgery was associated with a lower incidence of surgical site infections (SSIs) than laparoscopic surgery (0 vs. 7%, p = 0.028). There were no cases of anastomotic leakage after robotic surgery. The circumferential resection margin was involved in 0.8% of the patients who underwent robotic surgery; the incidence did not differ among the treatment groups.

conclusionsAlthough robotic surgery for rectal cancer was associated with a longer operation time, it was associated with a very low incidence of SSIs. The degree of safety was comparable to both open and laparoscopic surgery.
