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

backgroundGiven that a surgeon's technical skills affect not only short- but also long-term outcomes, adequate surgical training is very important. We developed the world's first training simulator for laparoscopic right hemicolectomy that does not use animal tissue, called COLOMASTER, which was designed to accurately reproduce the anatomical and membrane structures of the human body. Here, we report the features of COLOMASTER.

methodsDry polyester fibers were used to reproduce the multilayered membrane structure, and the adhesive strength of the layers was controlled using bonding technology, allowing realistic peeling techniques. Hydrogel was used to achieve electrical conductivity.

resultsCOLOMASTER allows surgeons to simulate the entire surgical step and practice complete mesocolic excision, central vascular ligation, and intracorporeal anastomosis, the importance of which has been reported in recent years.

conclusionWe present the world's first right hemicolectomy simulator that does not use animal tissue and believe that it will contribute to efficient off-the-job training.
