Hepatitis E Virus (HEV) Infection Among Pigs in Poland: An Assessment of the Prevalence on Commercial Swine Farms.

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 is a zoonotic infection related to consumption of virus-containing food of pig origin. Pigs are a natural reservoir of hepatitis E virus (HEV), and infected animals can enter the food chain. The study evaluated the prevalence of HEV infections in pigs raised on 30 commercial pig farms in Poland. Six hundred pooled samples of pig faeces were collected from fatteners (440), gilts (69) and dry sows (91). For HEV detection a one-step real-time reverse-transcription PCR (real-time RT-PCR) method with an incorporated target-specific internal amplification control was used. Subtype identification of the detected HEV strains was based on amplification and phylogenetic analysis of the open reading frame (ORF) 2 region in the virus genome. Viral RNA was detected in 161 (26.8%; 95% confidence interval [CI]: 23.3-30.6) samples of pooled pig faeces. Fattener pigs were by far the most prevalently infected (35.9%; 95% CI: 31.4-40.6; odds ratio [OR] = 18.7, 95% CI: 4.9-159.6), and gilts were markedly less so (2.9%; 95% CI: 0.3-10.1; OR = 0.05, 95% CI: 0.006-0.20). HEV-positive pigs were raised on fattening units (OR = 1.6, 95% CI: 1.1-2.4) and farrow-to-finish farms (OR = 0.6, 95% CI: 0.4-0.9) without any differences in prevalence of infections associated with farm type (χ
