Effects of estradiol on the virulence traits of Porphyromonas gingivalis.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Porphyromonas gingivalis has been strongly associated to active periodontitis sites. A number of studies have tried to elucidate the association between female steroid sex hormones and gingival health. However, until now, there is limited knowledge on estradiol effects on the virulence traits of P. gingivalis. The aim of the study was to investigate the impact of estradiol exposure on the virulence characteristics of P. gingivalis strain W50. We found that a pre- and postmenopausal concentration of estradiol increased the growth and biofilm formation of P. gingivalis W50. We also found that estradiol increased the release of lysine and arginine gingipains from W50. We then showed that IL-1β, CXCL10 and TGF-β1 release from gingival epithelial cells was significantly lowered by W50 pre-exposed to estradiol compared to W50 alone. Real time-qPCR showed that the gene expression of IL-18, IL-6, IL-8, TGF-β1 and NLRP3 in gingival epithelial cells was significantly lowered by W50 pre-exposed to estradiol compared to W50 alone. We also found that estradiol in a dose-dependent manner increased P. gingivalis colonization and invasion of gingival epithelial cells. Taken together, our findings show that estradiol has the ability to alter the virulence traits of P. gingivalis.
