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

backgroundNo randomized comparative trials have presented long-term outcomes for laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The present study was designed to compare the efficacy and safety of these two procedures.

methodsFrom January 2007 to July 2008, 64 eligible patients were randomly assigned to LSG or LRYGB. During the 5-year follow-up, we compared morbidity rate, body mass index (BMI), percent of excess weight loss (%EWL), Moorehead-Ardelt (M-A) II quality of life, and resolution or improvement rate of obesity-related comorbidities between the groups.

resultsBoth groups were matched with respect to age, gender, and BMI. Slightly more major complications were observed in patients undergoing LRYGB (P > 0.05). Weight loss was significantly better with LRYGB except during the first postoperative year. At 5 years, %EWL for LSG and LRYGB was 63.2 ± 24.5 % and 76.2 ± 21.7 % (P = 0.02), respectively. No statistical difference was observed in quality of life between the groups at all intervals (P > 0.05). At the last follow-up, most comorbidities in both groups were resolved or improved, with no difference between the groups (P > 0.05).

conclusionLRYGB and LSG are equally safe and effective in quality of life and improvement or resolution of comorbidities, and LRYGB possesses the superiority in terms of weight loss. Further studies are needed to evaluate micronutrient deficiencies of these procedures.
