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

purposeSleeve gastrectomy (SG) is the most performed bariatric procedure. Conversion to Roux-en-Y gastric bypass (RYGB) for SG-related complications such as gastroesophageal reflux disease (GERD), insufficient weight loss (ISWL), and weight regain (WR) is increasing. Our aim was to investigate the safety, efficacy, and outcomes of conversion from SG to RYGB.

methodsA literature search was performed from database inception to May 2020. Eligible studies must report indications for conversion, %total body weight loss (%TWL), and/or complications. The pooled mean or proportion were analyzed using a random-effects model.

resultsSeventeen unique studies (n = 556, 68.7% female, average age at time of conversion 42.6 ± 10.29 years) were included. The pooled conversion rate due to GERD was 30.4% (95% CI 23.5, 38.3%; I

conclusionThis meta-analysis showed that conversion from SG to RYGB is an option for conversion at a bariatric care center that produces sufficient weight loss outcomes, and potential resolution of symptoms of GERD. Further indication-based studies are required to obtain a clearer consensus on the surgical management of patients seeking RYGB following SG.
