Development of novel SARS-CoV-2 viral vectors.
Article in Scientific reports, 2023. 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
The authentic SARS-CoV-2 requires to be handled in Biosafety Level 3 laboratories, which restrains investigation by the broader scientific community. Here, we report the development of a novel SARS-CoV-2 viral vector composed of all 4 SARS-CoV-2 structural proteins, the packaging signal sequence of SARS-CoV-2, a reporter gene, and an RNA amplification component of Venezuelan equine encephalitis virus (VEEV). This VEE-SARS-CoV-2 viral vector transduces target cells in an ACE2-dependent manner, and all 4 structural proteins of SARS-CoV-2 are indispensable for its transduction activity. Comparative studies show that the incorporation of the VEEV self-amplification mechanism increases the gene expression level by ~ 65-fold and extends the transgene expression up to 11 days in transduced cells. Additionally, we demonstrated the significant applications of this new VEE-SARS-CoV-2 vector for neutralizing antibody quantification and antiviral drug testing. The VEE-SARS-CoV-2 vectors developed will be an important and versatile tool for investigating SARS-CoV-2 molecular virology, developing antiviral agents targeting receptor binding, and studying RNA genome packaging and function of the essential but not well studied structural proteins of SARS-CoV-2.
