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) is a relatively new surgical technique for the treatment of morbid obesity. It is unclear whether the volume of the gastric remnant can expand after surgery as a result of intraluminal pressure maintained over time. If this were the case, the increased volume could affect weight loss and the improvement in comorbidities. This study aims to assess the evolution of residual gastric volume (RGV) during the first year after LSG and its relationship with weight loss. MATERIAL AND

methodsWe conducted a prospective study of 112 patients who underwent LSG from February 2009 to December 2013. In order to measure the RGV after surgery, all patients were evaluated radiologically by an esophagogastroduodenal (EGD) transit at 1 and 12 postoperative months.

resultsAll patients showed a significant reduction in BMI compared with the preoperative measurement (33.48 ± 5.78 vs. 50.54 ± 6.69 kg/m

conclusionsThe volume of the gastric remnant increased significantly during the first year after LSG. However, this increase was not associated with weight loss. Further prospective research with longer follow-up periods is needed to confirm or contrast the present results.
