In vitro evaluation of disease-modifying antirheumatic drugs against rheumatoid arthritis associated pathogens of the oral microflora.

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
objectivesIn the past, the human microbiome has consistently been associated with rheumatoid arthritis (RA) and disease activity. Here, we investigate the antimicrobial activity of disease-modifying antirheumatic drugs (DMARDs) against typical representatives of the oral microflora that have been associated with RA.
methodsDMARDs were screened for antimicrobial activity against bacteria that are associated with the pathogenesis of the disease and/or frequently isolated from the oral microflora of patients with RA. Screening was done by an agar diffusion assay and minimum inhibitory concentrations (MICs) of antimicrobial active substances were then determined by broth dilution.
resultsAurothiomalate and sulfasalazine demonstrated broad-spectrum antimicrobial activity, but with MICs ranging from 18 to >280 µg/mL and 150 to >600 µg/mL, respectively, only at supratherapeutic concentrations. Methotrexate showed antimicrobial activity only against
conclusionMethotrexate, sulfasalazine and aurothiomalate showed antimicrobial activity against a broad spectrum of RA associated pathogens of the oral microflora. While methotrexate showed relevant antimicrobial activity, and to a more limited extent aurothiomalate, sulfasalazine was active only at far supratherapeutic systemic concentrations. Nevertheless, given the highly species-dependent antimicrobial activity and the multiple ways it can affect the human microbiome, our results suggest a link between antimicrobially active antirheumatic drugs and their potential effect in the treatment of RA.
