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

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are two most common weight loss procedures; our meta-analysis aims to compare these two in the treatment of morbid obesity and its related comorbidities. An electronic literature research of published studies concerning LRYGB and LSG was performed from inception to October 2013. Percentage of excess weight loss (%EWL), resolution or improvement rate of comorbidities, and adverse events were all pooled and compared by the software Review Manager 5.1. As a result, a total of 21 studies involving 18,766 morbidly obese patients were eventually selected according to the inclusion criteria. No significant difference was found in %EWL during 0.5- to 1.5-year follow-up (P > 0.05), but after that, LRYGB achieved higher %EWL than LSG (P < 0.05). Except for type 2 diabetes mellitus (T2DM) (P < 0.001), the difference between these two procedures in the resolution or improvement rate of other comorbidities did not reach a statistical significance (P > 0.05). There were more adverse events in LRYGB compared with LSG (P < 0.01). In conclusion, LRYGB is superior to LSG in efficacy but inferior to LSG in safety.
