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
Background: Bovine hepacivirus (BovHepV) is a recently identified member of the expanding genus Methods: In this study, serum samples from cattle and sheep were obtained in Hulunbuir and pooled to establish RNA libraries, which were then analyzed using transcriptome sequencing. BovHepV-positive samples were confirmed using semi-nested PCR with primers designed based on the obtained viral sequences. Comprehensive bioinformatics analyses were employed to assess sequence similarity, phylogenetic evolution, and recombination of the obtained viral strains. Results: A total of 988 serum samples from sheep (520) and cattle (468) were collected from 12 administrative districts in Hulunbuir from June to August, 2022. Semi-nested PCR revealed 6 BovHepV-positive districts with prevalence ranging from 2.0% to 35.0% in cattle, and one BovHepV-positive district with prevalence of 2.5% in sheep. The nucleotide sequence identities between viral strains from sheep and cattle ranged from 91.3% to 93.8%, while the amino acid sequence identities were between 95.4% and 96.7%. Phylogenetic analyses classified the obtained BovHepV strains within subtype G, genotype 1. Recombination analysis revealed the intergenerational relationships among the viral strains obtained from cattle and sheep. Conclusion: We identified genetic diversity in subtype G strains in cattle and detected a BovHepV strain in a sheep for the first time in northeastern China, confirming cross-species transmission and co-circulation between cattle and sheep, thus expanding the virus's host range.
