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

backgroundThe endoluminal mechanical device SatiSphere is a new endoscopically implantable device designed to delay transit time of nutrients through the duodenum. It consists of a 1-mm nitinol wire with pigtail ends and several mesh spheres mounted along its course, released in the duodenum and gastric antrum to conform to the duodenal C loop configuration and thereby self-anchor.

methodsThe objective is to test the safety, efficacy, and effect on body weight in a 2:1 randomized study, as well as incretin secretion in a subgroup.

resultsOf 31 included cases (11 men, mean age 42.9 years, mean BMI 41.3 kg/m2), 21 patients treated with endoscopic device insertion with scheduled device removal after 3 months were compared with 10 controls. In 10 of 21 patients, device migration occurred, in two cases necessitating emergency surgery, which led to termination of the trial. Weight loss after 3 months was 6.7, 4.6, and 2.2 kg in the groups completing therapy, all treatment cases using intention to treat (ITT) analysis and controls. Excess weight loss was significantly increased by endoluminal mechanical device insertion (18.4, 12.2, and 4.4% in completers, ITT analysis group and controls; p = 0.02 for completers vs. controls). Measuring glucose, insulin, and glucagon-like peptide 1 (GLP-1) following a mixed-meal test with the device in place and after removal (n = 7), the device delayed glucose absorption and insulin secretion and altered kinetics in GLP-1 levels.

conclusionsThe device might be short-term effective in reducing body weight, which might be mediated through alterations in incretin metabolism. However, frequent device migration necessitates device modifications.
