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

objectivesPeriodontal disease, a global health concern, is strongly associated with oral treponemes. However, the taxonomy of some species remains unresolved, hindering our understanding of their roles in disease. This study aims to clarify the taxonomy of three strains isolated from patients with periodontal disease using phylogenomic and comparative genomic analyses. MATERIALS AND

methodsWe performed genome sequencing for OMZ 800 and conducted phylogenomic and comparative genomic analyses of multiple strains to clarify their taxonomy.

resultsPhylogenomic and in-silico genome comparisons confirmed OMZ 800 as "T. vincentii" (Average Nucleotide Identity [ANI]>95%). We designated OMZ 800

conclusionThis study clarifies Treponema taxonomy by designating OMZ 800
