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

backgroundWhile changes in the gut microbiota have been reported in multiple sclerosis (MS), little is known about the nasal and oral microbiota, which are important modulators of the mucosal immune system. The gingival microbiota can drive systemic inflammation, the pharyngeal microbiota can lead to autoimmune-mediated neurologic diseases, and altered nasal bacterial toxigenic genes are reported in active MS.

methodsWe investigated nasal, gingival, and oropharyngeal microbiota from 69 MS to 40 healthy control subjects by 16S rRNA sequencing and identified site-specific microbiota differences in both the nasal and oral microbiota related to relapsing and progressive MS. We identified microbes associated with MS diagnosis, disease progression, disease modifying therapy, smoking, and anatomical site using linear regression analysis while controlling for confounding factors and subject demographics.

findingsWe identified site-specific microbiota differences in both the nasal and oral microbiota related to relapsing and progressive MS. Using baseline microbiota samples and clinical outcomes over time, we identified potential beneficial microbes, including Dolosigranulum pigrum in the nasal microbiota and Prevotella sp. in the oral microbiota, as well as potential detrimental Streptococcus sp. in the oral microbiota.

interpretationTaken together, our data suggest that nasal and oral microbiota are altered in MS, are linked to the disease course and provide an avenue to better understand MS pathogenesis and treatment.
