Comparison of Two Types of Liver Retractors in Laparoscopic Roux-en-Y Gastric Bypass for Morbid Obesity.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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.
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
backgroundRetraction of the left lobe of the liver is an important step in most bariatric surgical procedures. Bariatric patients may have enlarged, fatty livers and retraction can be complicated with injuries, haematoma, or necrosis. The aim of this study was to compare the effects of two standard liver retractors, Nathanson and PretzelFlex on patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB).
methodsAll consecutive patients undergoing LRYGB in our center from April 2017 to January 2019 were analysed. The type of retractor used was dependent on the surgeon's preference and the availability of instruments. Patients were divided into two groups, based on the type of liver retraction device used. Each group was assessed and compared for postoperative pain score, presence of nausea or vomiting, blood test results (liver function tests and C-reactive protein), and length of hospital stay.
resultsLRYGB was performed on 167 patients in which Nathanson was used in 93 patients and PretzelFlex in 74 patients. The duration of surgery was similar in both groups. Alanine transaminase (ALT) levels and C-reactive protein (CRP) were significantly higher in the group where Nathanson's retractor was used. The postoperative pain score and length of stay were also higher when Nathanson's retractor was used but it did not reach statistical significance.
conclusionThe PretzelFlex liver retractor causes significantly less measurable liver damage and is associated with less postoperative pain and nausea when compared with Nathanson's retractor.
