Rapid reconstruction of porcine reproductive and respiratory syndrome virus using synthetic DNA fragments.
Article in Computational and structural biotechnology journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most challenging infectious disease of pig populations causing devastating economic loss to swine industry. Reverse genetics allow to engineer modified viruses such attenuated strains for vaccine development. Some reverse genetic systems were described for PRRSVs but, due to genome complexity of PRRSVs, construction and modification of such systems remain laborious and time-consuming. In this study, we described a reverse genetics approach based on the "Infectious-Subgenomic Amplicons" (ISA) method to rescue infectious PRRSV particles. Permissive cells were transfected with 4 overlapping synthetic DNA fragments covering the entire genome of PRRSV which allowed the rapid reconstruction of the complete virus genome and the subsequent generation of infectious wild-type particles within days. The ISA method represent a rapid alternative of conventional reverse genetic systems. This method will help to generate genetically modified and attenuated strains for the development of sanitary countermeasures in the future.
