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

objectiveTo explore the diversity and composition of the fecal microbiota in patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.

methodsWe enrolled 10 patients in the acute stage with naïve treatment, seven patients with relapse, 13 patients without relapse in the remission phase, and 12 paired healthy controls. The fecal microbiota in different groups was compared by 16S ribosomal DNA (rDNA) gene pyrosequencing.

resultsProminent dysbiosis in the gut microbiome of patients with anti-NMDAR encephalitis was found. Our primary findings showed that the overall species richness (alpha diversity indexes) of the microbiota was higher in patients than in controls (P < 0.05). Distance-based community analysis revealed that the microbiota differed substantially within all subgroups of patients and controls (P < 0.05). The relative abundance of species heatmap showed a tendency toward depletion for some commensal genera, such as Prevotella_6, Bifidobacterium, Faecalibacterium, and other short-chain fatty acid (SCFA)-producing bacteria. Additionally, our results showed that all subgroups had a distinct bacterial species, with an increase in the genus Fusobacterium in the acute phase group and the genera Streptococcus and Parabacteroides in patients with relapse. However, the genus Bacteroides was very abundant in patients without relapse. Although the findings regarding the Firmicutes/Bacteroidetes (F/B) ratios across the four comparison groups were not statistically significant, the F/B ratio gradually increased in patients from the acute phase group (0.87), to the disease remission group with relapse (1.06), to the group without relapse (1.28), to the healthy group (1.63).

interpretationPatients with anti-NMDAR encephalitis exhibit a substantial alteration in fecal microbiota composition.
