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

purposeRobot-assisted surgery has been widely adopted for treating colorectal cancer (CRC). The Hugo™ robotic-assisted surgery (Hugo) system is a novel modular robotic platform; however, clinical data regarding its use for CRC remain limited. This study aimed to evaluate the perioperative and short-term outcomes of surgery for CRC using Hugo.

methodsIn this single-center, retrospective observational study, consecutive patients with CRC who underwent Hugo-assisted surgery were included. The clinicopathological characteristics and short-term outcomes were analyzed. All procedures were performed by or under the supervision of a surgeon with substantial experience in robot-assisted colorectal surgery.

resultsA total of 118 patients were included (57 with colon cancer and 61 with rectal cancer). The median operative times were 281 and 328 min for colon and rectal cancers, respectively. There were Clavien-Dindo Grade II complications in three patients with colon cancer and six with rectal cancer, and Grade III complications in two patients in the colon and one in the rectal cancer group. There were no intraoperative complications or conversions to open surgery.

conclusionsHugo-assisted surgery for CRC is feasible and safe. As the largest single-center series reported to date, this study provides important clinical evidence supporting the applicability of Hugo.
