Oral Microbiome in Systemic Autoimmune Diseases: A Systematic Review.

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
objectiveThe oral cavity represents a key but underexplored interface between host immunity and microbial communities. The aim of this systematic review was to synthesize current literature on oral microbiota alterations in systemic autoimmune diseases.
methodsPubMed and Web of Science databases were searched for human studies published between January 2000 and April 2025. Eligible observational studies compared adults with diagnoses of systemic autoimmune diseases to controls and characterized oral microbiota diversity and/or composition using sequencing-based methods. Different oral habitats were analyzed (saliva, dental plaque, oral mucosa, gingival crevicular fluid).
results42 studies met inclusion criteria: 19 on rheumatoid arthritis, 18 on primary Sjögren's syndrome, 5 on systemic lupus erythematosus, and 1 on anti-neutrophil cytoplasmic autoantibody-associated vasculitis. 16S rRNA gene sequencing predominated and only 3 studies used shotgun metagenomics, among which one also profiled the oral virome. Across systemic autoimmune diseases, dysbiosis was characterized by enrichment of anaerobic genera (Prevotella, Veillonella) and depletion of commensals (Neisseria, Haemophilus), with distinct β-diversity separation from controls. Periodontal disease and reduced salivary secretion significantly modulated microbial communities but did not fully explain disease-associated alterations.
conclusionThe oral microbiome exhibited shared dysbiotic signatures. However, methodological and clinical heterogeneity limited direct comparison between studies.
