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

We aim to review the available literature on obese patients treated with bariatric procedures, in order to assess their effect on the metabolic and gut microbiota profiles. A systematic literature search was performed in PubMed, Cochrane library, and Scopus databases, in accordance with the PRISMA guidelines. Twenty-two studies (562 patients) met the inclusion criteria. This study points to significant amelioration of postoperative levels of glucose, insulin, triglycerides, total cholesterol, LDL, HDL, HOMA-IR, food intake, and diabetes remission. Branched-chain amino acids (BCAAs) decreased, while trimethylamine-n-oxide (TMAO); glucagon-like peptide 1, 2 (GLP-1, GLP-2); and peptide YY (PYY) increased postoperatively. Postoperative gut microbiota was similar to that of lean and less obese objects. Well-designed randomized trials are necessary to further assess the host metabolic-microbial cross-talk after bariatric procedures.
