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

Hepatitis C virus (HCV) infection frequently leads to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. There is no effective therapy or vaccine available to HCV-infected patients other than interferon-ribavarin combination, which is effective in a relatively small percentage of infected patients. Our previous results have shown that a synthetic peptide (LAP) corresponding to the N-terminal 18 amino acids of the Lupus autoantigen (La) was a potent inhibitor of HCV IRES-mediated translation. We demonstrate here that LAP efficiently blocks HCV replication of infectious JFH1 virus in cell culture. Our data suggest that LAP forms complexes with IRES-transacting factors (ITAFs) PTB and PCBP2. LAP-mediated inhibition of HCV IRES-mediated translation in vitro could be fully rescued by recombinant PCB and PCBP2. Also transient expression of PTB / PCBP2 combination significantly restores HCV replication in LAP-inhibited cultures. These results suggest that ITAFs could be potential targets to block HCV replication.
