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
backgroundTrichomonosis is a common infection in small animals, mostly manifesting in gastrointestinal symptoms such as diarrhea. Although oral trichomonads are also known, the species found colonizing the large intestine are more frequently detected protozoa.
methodsIn the present study, four wildcats, 94 domestic cats, and 25 dogs, originating from 18 different locations in Hungary, were investigated for the presence of oral and large intestinal trichomonads based on the 18S rRNA gene and ITS2.
resultsAll oral swabs were negative by polymerase chain reaction (PCR). However, Tritrichomonas foetus was detected in a high proportion among tested domestic cats (13.8%) and dogs (16%), and Pentatrichomonas hominis only in two domestic cats. In addition, a novel Tritrichomonas genotype was identified in one cat, probably representing a new species that was shown to be phylogenetically most closely related to Tritrichomonas casperi described recently from mice. All positive dogs and half of the positive cats showed symptoms, and among cats, the most frequent breed was the Ragdoll.
conclusionsWith molecular methods, this study evaluated the prevalence of oral and intestinal trichomonads in clinical samples of dogs and cats from Hungary, providing the first evidence of T. foetus in dogs of this region. In contrast to literature data, P. hominis was more prevalent in cats than in dogs. Finally, a hitherto unknown large intestinal Tritrichomonas species (closely related to T. casperi) was shown to be present in a cat, raising two possibilities. First, this novel genotype might have been a rodent-associated pseudoparasite in the relevant cat. Otherwise, the cat was actually infected, thus suggesting the role of a predator-prey link in the evolution of this trichomonad.
