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

purposeRetraction of the left lobe of the liver is an important step in most bariatric surgical procedures. The left lobe of the liver may be enlarged, and laceration, hematoma, or necrosis may develop in the liver due to retraction. In this study, the results of use of the Nathanson retractor (NR) and PretzelFlex retractor (PFR) in the patients undergoing laparoscopic sleeve gastrectomy (LSG) were compared. MATERIALS AND

methodsThe patients who underwent LSG were divided into three groups based on the type of liver retraction device used. Group 1: NR was used fixed during the operation; Group 2: PF retractor was used; Group 3: NR were used only for fundus dissection and when necessary. All groups were evaluated in terms of demographic characteristics, liver function tests, and developing complications.

resultsThe study was conducted with a total of 120 consecutive patients. Operation time in the second group was found to be significantly lower than the other two groups (p = 0.009; p = 0.001; p < 0.01). The duration of retractor use in the first group was significantly higher than the other two groups (p = 0.001; p = 0.001; p < 0.01). While aspartate aminotransferase (AST) values were found to be high in Group 1, alanine aminotransferase (ALT) values were found to be high in Groups 1 and 3.

conclusionPFR has shorter operating and retraction times. It causes less measurable liver damage. Although the NR will be used, intermittent use causes less damage to the liver as in PFR.
