Detection and isolation of genotype 3 subtype b hepatitis E viruses from wild boars in Japan.
Article in The Journal of veterinary medical science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
To conduct an epidemiological study of hepatitis E virus (HEV) in Japanese wild boars, we collected 179 serum and 162 fecal specimens from wild boars in eight Japanese prefectures; 39 of the serum samples (21.8%) were positive for anti-HEV IgG antibodies. RT-qPCR revealed HEV RNA in 11 serum samples (6.1%) and 5 fecal samples (3.1%). We obtained 412 bp of the viral genome sequences of ORF2 from five pairs of serum and fecal samples. All strains were subtype b in genotype 3 (HEV-3b) but separated into different clusters. We determined the entire genome sequence of HEV-3b strain WB0567 using a fecal specimen and isolated this strain by cell culture using PLC/PRF/5 cells. Eleven nucleotide mutations had occurred during virus replication. These results suggest that HEV-3b circulated uniformly among wild boars in Japan. Direct sequencing using a suspected animal's samples is indispensable for predicting original HEV nucleotide sequences.
