Oral, not gut microbiota diversity, reflects the inflammation and neoplasia in patients with uveitis and vitreoretinal lymphoma.

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.
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
purposeDysregulation of the microbiota on different mucosal surfaces is associated with both immune-mediated and malignant diseases. Nevertheless, the involvement of different microbial communities is still poorly characterized. The aim of our study was to compare oral and gut microbiota composition between patients with uveitis, vitreoretinal lymphoma (VRL), and controls.
methodsThis study was designed as a prospective observational study. The inclusion criteria were treatment-naïve patients with immune-mediated uveitis or newly diagnosed VRL. The buccal swab and faecal samples were collected and bacterial 16S ribosomal RNA gene sequencing was used to identify the oral and gut microbiota.
resultsWe enrolled 18 patients with uveitis, median age 39 years, 16 patients with VRL, median age 67.5 years, and 16 controls, median age 63 years. In the oral microbiota, the patients suffering from uveitis showed significant enrichment of genera Pseudomonas (p < 0.0001 and p < 0.0001), and Diaphorobacter (p = 0.007 and 0.013) and reduction of Streptococcus (p < 0.0001 and p < 0.0001) when compared to patients with VRL and control subjects, respectively. In addition, these patients had also significantly higher relative abundance of the genus Enhydrobacter (p = 0.029) and lower abundance of the genera Gemella (p = 0.002), Neisseria (p = 0.008), and Prevotella (p = 0.011) when compared to patients with VRL. We found only minor changes in the gut microbiota.
conclusionOur study, as the first one, highlighted significant differences in the composition of oral microbiota among patients with uveitis, VRL, and control subjects.
