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

backgroundRecent scientific evidence indicates that the oral-gut axis represents a critical interface in host-microbiota interactions, carrying profound implications for both periodontal and gastrointestinal diseases. This scoping review aims to evaluate the reciprocal influence between periodontitis and inflammatory bowel disease (IBD). Specifically, the underlying mechanisms of microbial translocation, immune interaction, and metabolite-mediated signaling linking the oral microbiota to gut microbial ecology are critically evaluated.

methodsStudies were selected from the PubMed, Web of Science, and Scopus databases up to May 2026. Eligible criteria included in vivo studies written in English and conducted within the last 10 years, whereas human studies involving participants under 18 years of age were excluded. The included studies analyze the effects of oral and gut dysbiosis on the opposing district. Through the database search, 2094 records were identified, and 34 articles were selected based on the eligibility criteria.

resultsThe included studies demonstrate the interconnection between the oral and gut microbiota. The included studies reveal that predominant oral taxa, specifically

conclusionsUnderstanding these interconnected microbial ecosystems provides valuable insights that may support the future development of integrated diagnostic and therapeutic strategies for patients suffering from periodontitis and IBD. Further large-scale studies with longer follow-up periods are required to standardize potential salivary markers and multidisciplinary therapeutic protocols for the management of periodontitis and IBD.
