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

Beta interferon (IFN-beta) expression is triggered by double-stranded RNA, a common intermediate in the replication of many viruses including hepatitis C virus (HCV). The recent development of cell culture-grown HCV allowed us to analyze the IFN signaling pathway following virus infection. In this study, we have examined the IFN-beta signaling pathway following infection of immortalized human hepatocytes (IHH) with HCV genotype 1a (clone H77) or 2a (clone JFH1). We observed that IHH possesses a functional Toll-like receptor 3 pathway. HCV infection in IHH enhanced IFN-beta and IFN-stimulated gene 56 (ISG56) promoter activities; however, poly(I-C)-induced IFN-beta and ISG56 expression levels were modestly inhibited upon HCV infection. IHH infected with HCV (genotype 1a or 2a) exhibited various levels of translocation of IRF-3 into the nucleus. The upregulation of endogenous IFN-beta and 2',5'-oligoadenylate synthetase 1 mRNA expression was also observed in HCV-infected IHH. Subsequent studies suggested that HCV infection in IHH enhanced STAT1 and ISG56 protein expression. A functional antiviral response of HCV-infected IHH was observed by the growth-inhibitory role in vesicular stomatitis virus. Together, our results suggested that HCV infection in IHH induces the IFN signaling pathway, which corroborates observations from natural HCV infection in humans.
