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

importancePseudorabies (PR) is a significant disease that adversely affects the healthy growth of the pig industry in China. However, data on molecular epidemiology and genetic characterization of PRV is sparse.

objectiveThis study examined the epidemic trends and variation characteristics of the PR virus (PRV) in Henan Province of China.

methodsSix hundred eighty-eight clinically infected pig tissue samples were collected from 18 cities in Henan Province from January 2021 to March 2023 and tested for the PRV. The PRV was isolated from positive samples and identified by a polymerase chain reaction and immunofluorescence assay. The

resultsThe positive rate of PRV nucleic acid was 7.99% (55/688) in Henan Province, China. This study isolated eight PRV strains, all of which were genotype II variants. Seven isolates displayed unique amino acid mutations in the gC or gE proteins. The isolates of G22, HN4, QX, and QX2 can cause acute neurological symptoms in KM mice, with 50% lethal dose values of 10 CONCLUSIONS AND RELEVANCE: This study revealed a high prevalence of the PRV in Henan Province, with genotype II variants being the predominant strains. These findings provide essential data for the prevention and control of the PRV.
