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

Knowledge about fish-pathogen interaction is essential for optimizing technical and biological aspect of culture techniques to guarantee the economic viability of the aquaculture production. Nodavirus (NNV) is one of the most prevalent viruses worldwide causing disease in more than 170 species. In this study, we aimed to develop a non-lethal method to diagnose NNV in the gonad of asymptomatic broodstock specimens of greater amberjack (Seriola dumerili) using a RTG cell line expressing the luciferase reporter gene under the control of the Mx promoter (RTG-pmx-luciferase system) and real-time PCR. We also characterize the immune response and reproductive health of both sexes by means of gene expression and functional parameters analysis. Our data showed that NNV is present in both male and female blood and gonads in similar proportions demonstrating that both sexes might develop persistent infection and transfer the virus to their progeny by vertical transmission. Regarding immune response, the levels observed in the testis were higher in infected males. Specifically, we observed an up-regulation of genes related to the interferon pathway, antimicrobial peptides and leucocyte-markers molecules in infected testis, which might lead to a functional alteration. Otherwise, there were no alterations of immune parameters in the infected ovaries suggesting a latent infection. Serum estradiol levels were high in infected females constituting a potential mechanism to fight against the virus. In conclusion, we optimized a non-lethal method for NNV diagnosis involving gonadal biopsies. Moreover, our study revealed sex-biased host-NNV interactions.
