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

Kobuviruses infect a wide range of hosts and exhibit high genetic diversity, highlighting the need for further studies to better understand their evolution and impact on animal health. In the present study, bovine kobuvirus (BKoV) was detected in 40 of 154 fecal samples from calves using the primers targeting the 3D gene region, corresponding to an overall positivity rate of 25.97%. All positive samples were obtained from diarrheic calves younger than 30 days of age, (40/133; 30.08%), consistent with previous studies. To enable more reliable genotyping, the complete VP1 gene sequences of seven BKoV strains were obtained, and the phylogenetic analyses showed that all VP1 sequences of this study clustered within Aichivirus B1. Additionally, immunoinformatics analysis of the VP1 protein identified conserved linear and discontinuous B-cell epitopes that may represent potential targets for cross-reactive diagnostic assays or future vaccine studies. The complete coding sequence of one strain, K056/2008/TUR, was also generated, and molecular analysis of this strain provided further evidence of ongoing viral evolution and genetic diversity in Türkiye. Overall, these findings provide new insights into the prevalence, genetic diversity, and predicted immunogenic features of BKoVs in calves in Türkiye, supporting further studies on its pathogenesis, diagnostics, and antigenic properties.
