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

backgroundLaparoscopic sleeve gastrectomy (LSG) has emerged as an effective weight-loss procedure for morbid obesity that is also effective for treating comorbidities such as diabetes. However, it has been associated with the development of GERD postoperatively. The pathophysiology of post-LSG GERD is unknown, and current studies have shown conflicting results. The aim of our study is to shed light on this issue by investigating the effect of LSG on the lower esophageal sphincter (LES) function and the relationship of LES function to GERD symptoms.

methodsA prospective study of patients undergoing LSG from 10/2013 to 8/2014 at a single academic tertiary referral center was carried out. Patients undergoing a concomitant procedure such as hiatal hernia repair or laparoscopic gastric band removal were excluded. Distensibility of the LES was measured after pneumoperitoneum and after LSG. Baseline GERD-HRQL was obtained with follow-up GERD-HRQL and weight at 3 and 6 months. The primary outcomes measured were LES distensibility and GERD-HRQL scores after LSG. Our secondary outcome was a correlation between LES distensibility and GERD-HRQL scores after LSG.

resultsFifteen subjects were enrolled (5M/10F). Mean age was 51 years (30-71 years), and mean BMI 45 kg/m

conclusionWhile LSG weakens the LES immediately, it does not predictably affect postoperative GERD symptoms; therefore, distensibility is not the only factor affecting development of postoperative GERD, confirming the multifactorial nature of post-LSG GERD.
