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

backgroundLiver retractor helps in the provision of an adequate operative field in bariatric surgery. Though several retractors have been introduced, an optimal retraction method is yet to be desired. We have developed a K-wire retractor, a simple trocar-free liver retractor used in our bariatric surgery. The efficacy and safety of the K-wire retractor were examined.

methodsA retrospective review was performed on patients undergoing laparoscopic bariatric surgery from January 2016 to April 2019. Based on the application of liver retractors during surgery, patients were divided into the K-wire retractor group and the suture-based retractor group for comparative analyses. Patients with severe liver injury or missing data, or treated with other types of retractors were excluded.

resultsA total of 317 patients were included in our study and there was no conversion to open surgery. There were no significant differences in patient demographics (age, gender, BMI) and types of bariatric surgery between the two groups. The time taken for placement of retractor was significantly shorter in the K-wire retractor group, in addition to higher operative view score and lesser ALT/AST elevation compared with the suture-based retractor group. Although the K-wire retractor group was less inclined to require additional retraction techniques, patients with BMI ≥ 50 Kg/m

conclusionThe trocar-free K-wire liver retractor is safe, simple, and effective as a standard liver retraction method in bariatric surgery.
