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

Progress in understanding hepatitis C virus (HCV) biology has remained a challenge due to the lack of an efficient cell culture system for virus growth. In this study, we examined HCV core protein-mediated immortalized human hepatocytes (IHH) for growth of HCV. In vitro-transcribed full-length RNA from HCV genotype 1a (clone H77) was introduced into IHH by electroporation. Reverse transcription-PCR of cellular RNA isolated from HCV genome-transfected IHH suggested that viral RNA replication occurred. IHH transfected with the full-length HCV genome also displayed viral protein expression by indirect immunofluorescence. In contrast, cells transfected with polymerase-defective HCV (H77/GND) RNA as a negative control did not exhibit expression of the viral genome. Immunogold labeling demonstrated localization of E1 protein in the rough endoplasmic reticulum of RNA-transfected IHH. Virus-like particles of approximately 50 nm were observed in the cytoplasm. After being inoculated with culture media of cells transfected with the full-length HCV genome, naïve IHH displayed NS5a protein expression in a dilution-dependent manner, but expression of NS5a was inhibited by prior incubation of culture medium with HCV-infected patient sera. NS5a-positive immunofluorescence of cell culture media of IHH transfected with full-length H77 RNA yielded approximately 4.5 x 10(4) to 1 x 10(5) focus-forming units/ml. A similar level of virus growth was observed upon transfection of RNA from HCV genotype 2a (JFH1) into IHH. Taken together, our results suggest that IHH support HCV genome replication and virus assembly.
