Development and characterization of a recombinant Senecavirus A expressing enhanced green fluorescent protein.

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
Introduction: Senecavirus A (SVA), belonging to the genus Methods: In this study, we established a reverse genetics system for a local SVA isolate and used it to rescue a recombinant SVA, rSVA-eGFP, expressing the enhanced green fluorescent protein (eGFP) by inserting eGFP, GSG linker and the P2A sequence between 2A and 2B genes. Results: We found that rSVA-eGFP exhibited a high replication efficiency comparable to the parental virus, was able to express the eGFP reporter efficiently and stable in maintaining the reporter gene up to six rounds of serial passages in BHK-21 cells. In mice, rSVA-eGFP also showed similar replication kinetics and pathogenicity to the parental virus, both causing mild lung lesions. In addition, a high-throughput viral neutralization assay was developed using eGFP as a surrogate readout in a fluorescence-based direct titration (FBT) assay based on rSVA-eGFP, facilitating rapid and accurate determination of the neutralizing antibody (nAb) titers. Discussion: The successful establishment of an SVA reverse genetics system and the rescue of rSVA-eGFP would create a powerful tool for future studies of SVA replication mechanisms and pathogenicity as well as for antiviral development.
