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

Understanding how the hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp) interacts with nascent RNA would provide valuable insight into the virus's mechanism for RNA synthesis. Using a peptide mass fingerprinting method and affinity capture of peptides reversibly cross-linked to an alkyn-labeled nascent RNA, we identified a region below the Δ1 loop in the fingers domain of the HCV RdRp that contacts the nascent RNA. A modification protection assay was used to confirm the assignment. Several mutations within the putative nascent RNA binding region were generated and analyzed for RNA synthesis in vitro and in the HCV subgenomic replicon. All mutations tested within this region showed a decrease in primer-dependent RNA synthesis and decreased stabilization of the ternary complex. The results from this study advance our understanding of the structure and function of the HCV RdRp and the requirements for HCV RNA synthesis. In addition, a model of nascent RNA interaction is compared with results from structural studies.
