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

In this study, we conducted an epidemiological investigation and analyzed the agreement between the Faust technique and the immunochromatographic assay in the diagnosis of Giardia spp. in 272 cats in the municipality of Londrina, Paraná state, Brazil. We identified an overall prevalence of 74.63% (203/272 [95% CI: 69.14-79.44%]) of Giardia spp. in cats, being significantly higher in adult and non-domiciled animals, which presented, respectively, 5.3 and 8.6 times more chances of infection when compared to kittens and domiciled animals. However, all the animals investigated that tested positive did not present with diarrhea. Regarding diagnostic methods, using coproparasitological examination, Giardia spp. cysts were observed in the feces of 193 cats, and through the immunochromatographic assay, coproantigens of this protozoan were detected in 203 samples, demonstrating almost perfect agreement (Kappa Cohen: 0.907). Thus, according to the authors' knowledge, this is the highest prevalence of Giardia spp. ever identified in cats in Brazil, and with regard to diagnostic methods, we observed a high concordance between the coproparasitological examination and the immunochromatographic assay in the detection of the aforementioned protozoan.
