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

introductionThe volume of the gastric reservoir (VGR) after sleeve gastrectomy influences weight loss in the short-term, but long-term results are scarce. The aim was to analyze the correlation between the VGR and weight loss at 5 years of follow-up.

methodsIt is a prospective observational study of 50 patients undergoing sleeve gastrectomy (SG) from February 2009 to December 2013. An upper gastrointestinal series was performed at 1 month and at 1 and 5 years after surgery. A composite formula was used for VGR estimation. Weight loss-related data included the following: body mass index (BMI), percentage of excess weight loss (%EWL), and percentage of excess BMI loss (%EBMIL) at 1 month and at 1 and 5 years. Uni- and multivariate analyses were carried out to determine other factors that might influence long-term weight loss results.

resultsThe %EWL at 1 year was 74.5(63.8-86) vs. 55.5(47-74.3) at 5 years (p < 0.001). The VGR 1 month after surgery was 114.9 (90.5-168.3) mL. The VGR increased from 216.7 (155.1-278.6) to 367.5 (273-560.3) mL (p < 0.001) at 1 and 5 years. Although a significant inverse correlation was observed between VGR and BMI, %EWL, and %EBMIL at 1 year, it disappeared at 5 years. In the multivariate analysis, the main factor to predict worse weight results at 5 years was a pre-surgical BMI ≥ 50 kg/m

conclusionThe VGR increased progressively during the study period. Although an inverse relationship between VGR and weight was found at 1 year, this correlation did not remain at 5 years. A preoperative BMI ≥ 50 kg/m
