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

backgroundThe present study was designed to characterize phenotypically and genotypically two Trueperella pyogenes strains isolated from an okapi (Okapia johnstoni) and a royal python (Python regius). CASE PRESENTATION: The species identity could be confirmed by phenotypic properties, by MALDI-TOF MS analysis and by detection of T. pyogenes chaperonin-encoding gene cpn60 with a previously developed loop-mediated isothermal amplification (LAMP) assay. Furthermore, sequencing of the 16S ribosomal RNA (rRNA) gene, the 16S-23S rDNA intergenic spacer region (ISR), the target genes rpoB encoding the β-subunit of bacterial RNA polymerase, tuf encoding elongation factor tu and plo encoding the putative virulence factor pyolysin allowed the identification of both T. pyogenes isolates at species level.

conclusionsBoth strains could be clearly identified as T. pyogenes. The T. pyogenes strain isolated in high number from the vaginal discharge of an okapi seems to be of importance for the infectious process; the T. pyogenes strain from the royal python could be isolated from an apparently non-infectious process. However, both strains represent the first isolation of T. pyogenes from these animal species.
