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

backgroundBariatric surgery is widely accepted as the best treatment for obesity and type 2 diabetes mellitus (T2DM). The Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG) have become the predominant bariatric procedures in the USA over the last several years, although the most recent trends in selection are unknown.

objectiveThe objective of this study is to assess selection trends, readmission rates, and cost of bariatric procedures in the USA from 2012 to 2015.

methodsWe used the Premier database from 2012 to 2015 to examine trends in incidence of RYGB, adjustable gastric banding (LAGB), and SG; readmissions; and cost. Multivariate regression was performed to identify predictors of readmission.

resultsThe proportion of SG went up from 38 to 63% while the RYGB decreased from 44 to 30% over this time period. LAGB has decreased in use from 13 to 2%. In comparison to RYGB, readmission was less likely for SG (OR 0.64), males (OR 0.91), and more likely for black race (OR 1.27). The overall proportion of patients seeking RYGB with type 2 diabetes was higher than with SG (36 versus 25%), but SG has now overtaken RYGB as the most common procedure among diabetics. The SG is less costly than RYGB ($11,183 versus $13,485).

conclusionsThere is a continued overall trend in the increased popularity of the SG and decreased utilization of the RYGB and LAGB, although growth of the SG appears to be slowing. This is also true among patients with type 2 diabetes mellitus. Regardless of surgery type, underinsured and African-American race were more likely to be readmitted.
