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

Dietary gluten triggers symptoms in patients with gluten-related disorders (GRDs) including celiac disease (CeD), non-celiac gluten sensitivity (NCGS), and subsets of patients with functional dyspepsia (FD). The gastrointestinal microbiota is altered in these patients when compared to healthy individuals. As the microbiota is crucial for the hydrolysis of gluten, we hypothesized that the capacity of the microbiota to digest gluten is reduced in these conditions. We systematically reviewed and re-analyzed published datasets to compare gastrointestinal microbiomes of GRD patients and identify signals explaining gluten responses. A systematic search of five databases was conducted to identify studies where the microbiota of CeD, NCGS, or FD patients was analyzed by 16S rRNA amplicon or shotgun metagenomic sequencing and compared to control populations. Where available, raw duodenal microbiota sequence data were re-analyzed with a consistent bioinformatic pipeline. Thirty articles met the inclusion criteria for this systematic review. Microbiota diversity metrics were not impacted by the diseases; however, genera including
