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

purposePrior studies have demonstrated that both dietary components and bariatric surgery modify the gut microbiota's composition. However, there is a scarcity of research that has examined the relationship between post-surgical dietary intake and changes in the gut microbiota. The aim of this study was to assess changes in gut microbiota following bariatric surgery and examine their association with postoperative dietary intake. MATERIALS AND

methodsThe present study involved a sample of 42 adult women who were potential candidates for bariatric surgery, i.e., laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG). The assessment of dietary intake was conducted through the use of three-day food records, both at baseline and six months following the surgical procedure. The gut microbiota was determined through the detection of 16S ribosomal RNA (16S rRNA) gene sequencing.

resultsAfter six months, a significant increase in abundance of Firmicutes (P = 0.01), Bifidobacterium (P = 0.01), and Ruminococcus (P = 0.04) in the LSG group was found. In contrast to the observed rise in Enterobacteria (P = 0.02) levels in the LRYGB group, no significant changes were detected in the composition of other gut microbiota over the 6-month monitoring period subsequent to LRYGB. The results of our study indicate that there is not a statistically significant relationship between dietary consumption and changes in the composition of the gut microbiota in individuals who have undergone LRYGB and LSG.

conclusionOur findings suggest that there may not be a significant correlation between dietary intake following LRYGB and LSG, and the observed alterations in the gut microbiota during a six-month period of observation. Nevertheless, it is important to acknowledge that the sample size utilized in our study was limited, potentially leading to reduced statistical power and the possibility of yielding findings that do not accurately reflect reality.
