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

objectiveThis study aimed to investigate the diversity, composition, and functional characteristics of the gingival crevicular fluid (GCF) microbiota in individuals with periodontitis, peri-implantitis, and healthy controls (Groups P, PI, and H, respectively), and to identify potential biomarkers specific to PI. MATERIALS AND

methodsGCF samples were collected from nine participants diagnosed with periodontitis, peri-implantitis, or classified as healthy. Microbial communities were analyzed using 16 S ribosomal RNA (rRNA) gene amplicon sequencing to profile the plaque microbiota.

resultsGroups P and PI showed significantly higher species richness than Group H. Principal coordinates analysis revealed that the microbial composition of Group PI was more similar to Group P than Group H. Firmicutes were enriched in Group PI at the phylum level, whereas Neisseria, Veillonella, Streptococcus, Haemophilus, and Prevotella were dominant at the genus level. Linear discriminant analysis effect size analysis identified Proteobacteria, Prevotella, Prevotella_7, Actinobacillus, and Lachnoanaerobaculum as significantly enriched in Group PI. Functional prediction showed associations with energy metabolism, cell wall synthesis, and amino acid synthesis. BugBase analysis revealed distinct phenotypic microbiota profiles in Group PI. Spearman correlation analysis indicated strong positive associations between PI-enriched genera and periodontitis-associated pathogens such as Fusobacterium.

conclusionThe microbiota of Group PI exhibits unique taxonomic and functional profiles. Prevotella and other taxa may serve as potential candidate biomarkers associated with PI. Their diagnostic efficacy and clinical applicability require further clarification through large-sample, multi-center validation studies. Functional enrichment in energy metabolism, cell wall synthesis, and amino acid synthesis pathways suggests a role in disease progression.
