Production of a chimeric flavivirus that contains the major structural glycoprotein genes of T'Ho virus in the genetic background of Zika virus.

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
T'Ho virus is a poorly characterized orthoflavivirus most closely related to Rocio virus and Ilheus virus, two orthoflaviviruses associated with human disease, suggesting that T'Ho virus could also be a human pathogen. The genome of T'Ho virus has been sequenced but an isolate has never been recovered, impeding its phenotypic characterization. In an attempt to generate recombinant T'Ho virus, the entire viral genome was synthesized as three overlapping DNA fragments, joined by Gibson assembly, and transfected into mosquito cells. Several cell culture passages were performed, but virus was not recovered. Subsequent experiments focused on the development of a chimeric orthoflavivirus that contains the premembrane and envelope protein genes of T'Ho virus in the genetic background of Zika virus. The chimeric virus replicated in mosquito (C6/36) and vertebrate (Vero) cells, demonstrating that the major structural glycoproteins of T'Ho virus permit entry into both cell types. The chimeric virus produced plaques in Vero cells that were significantly smaller than those produced by Zika virus. The chimeric virus can potentially be used as a surrogate diagnostic reagent in place of T'Ho virus in plaque reduction neutralization tests, allowing T'Ho virus to be considered in the differential diagnosis.
