Absence of hepatitis E virus RNA in bovines from Portugal.
Article in Veterinary research communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Hepatitis E virus (HEV) is widely recognized as an emerging public health issue in developed countries, with most infections linked to foodborne transmission of genotype HEV-3. This zoonotic genotype can infect a diverse range of mammalian species, including bovine, with pigs serving as the primary reservoir. The aim of the present study was to investigate the occurrence, circulation, and the potential of HEV infection among bovines in Portugal. Stool samples were collected from 166 bovines raised on extensive and intensive farms in Portugal, from June one to July 31, 2015. For the detection of HEV RNA a nested broad-spectrum RT-PCR targeting the ORF1 region was used. HEV RNA was not detected in any of the fecal samples analyzed. Although no HEV RNA was detected in bovine fecal samples, spiking of the samples with mengovirus demonstrated an acceptable RNA recovery rate, ensuring the reliability of RNA extraction and subsequent molecular analysis performed. Further research could provide additional insights into the factors influencing HEV transmission dynamics in bovines and its potential implications for public health.
