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

objectivePeriodontal disease (PD) is an established risk factor for rheumatoid arthritis (RA). The objective of this study is to identify how oral bacterial infections occurring in damaged periodontal tissue in PD can lead to joint inflammation and destruction in RA.

methodsFour separate commensal oral bacteria species were cultured with human neutrophils to induce neutrophil extracellular trap formation (NETosis). The resultant NETs contained neutrophil-derived peptidylarginine deiminase 4 (PAD4), which, within the NET milieu, became activated and mediated citrullination of both bacterial and neutrophil self-proteins. Citrullination was evaluated by adding rabbit anticitrulline antibody followed by Alexa Fluor 647-conjugated antirabbit IgG secondary antibody.

resultsOur data demonstrate that citrullinated oral bacteria induce Toll-like receptor 9 (TLR9)-spleen tyrosine kinase (Syk)-mediated human B cell activation, differentiation, proliferation, and antibody secretion, including the development of plasmablasts secreting anticitrullinated protein antibodies (ACPAs). Some ACPAs bind citrullinated oral bacteria to form immune complexes (ICs) that can activate monocyte-derived macrophages in vitro to differentiate into CD11b

conclusionOur data support the hypothesis that in RA patients with PD, citrullinated oral bacteria breach damaged periodontal tissue to enter the circulation and induce both innate and adaptive proinflammatory responses that promote synovial tissue destruction.
