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

Viral hemorrhagic septicemia virus (VHSV) and infectious hematopoietic necrosis virus (IHNV) are members of the genus Novirhabdovirus within the Rhabdoviridae family, which can cause severe hemorrhagic disease in fresh- and saltwater fish worldwide. These viruses carry an additional nonvirion (NV) gene, which codes for the nonstructural NV protein that has been implicated to play a role in viral pathogenesis. To determine the precise biological function of this NV gene and its gene product, we generated NV-deficient and NV knockout recombinant VHSVs, using reverse genetics. Comparisons of the replication kinetics and markers for virus-induced apoptosis indicated that the NV-deficient and NV knockout mutant viruses induce apoptosis earlier in cell culture than the wild-type recombinant VHSV. These results suggest that the NV protein has an antiapoptotic function at the early stage of virus infection. Furthermore, we created a chimeric VHSV, in which the NV gene of VHSV was replaced by the IHNV NV gene, which was capable of suppressing apoptosis in cell culture. These results show that the NV protein of other members of Novirhabdovirus can restore the NV protein function. In this study, we also investigated the kinetics of VHSV replication during a single round of viral replication and examined the mechanism of VHSV-induced apoptosis. Our results show that VHSV infection induced caspases 3, 8 and 9 in cell culture.
