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

Infections caused by the Chlamydiales order are highly prevalent worldwide and have a well-known association with reproductive and non-reproductive disorders in livestock and humans. This study aimed to identify Chlamydiales organisms in ruminant abortions using real-time polymerase chain reaction (qPCR) in samples collected from three Brazilian states: Rio Grande do Sul, Santa Catarina, and São Paulo. The Chlamydiales order was found in 7.8% (18/231) of the samples, including 10 bovine and 8 ovine samples. For the Chlamydiaceae family, the positivity was 2.2% (5/231), with detection in one bovine and two ovine fetuses from Rio Grande do Sul, one ovine fetus from Santa Catarina, and one bovine from São Paulo. Chlamydiales positive samples detection with Ct value lower than 35 were subjected to Sanger sequencing and phylogenetic analysis, which revealed the presence of an organism belonging to the Waddliaceae family in a bovine fetus and two Simkaneceae bacteria in ovine fetuses. This study is the first report of Chlamydia-like organisms in ruminant abortions in Brazil, highlighting the importance of conducting further surveys to evaluate their role as abortifacient pathogens in the country.
