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

DECH-box proteins are a subset of DExH/D-box superfamily 2 helicases possessing a conserved Asp-Glu-Cys-His motif in their ATP binding site. The conserved His helps position the Asp and Glu residues, which coordinate the divalent metal cation that connects the protein to ATP and activate the water molecule needed for ATP hydrolysis, but the role of the Cys is still unclear. This study uses site-directed mutants of the model DECH-box helicase encoded by the hepatitis C virus (HCV) to examine the role of the Cys in helicase action. Proteins lacking a Cys unwound DNA less efficiently than wild-type proteins did. For example, at low protein concentrations, a helicase harboring a Gly instead of the DECH-box Cys unwound DNA more slowly than the wild-type helicase did, but at higher protein concentrations, the two proteins unwound DNA at similar rates. All HCV proteins analyzed had similar affinities for ATP and nucleic acids and hydrolyzed ATP in the presence of RNA at similar rates. However, in the absence of RNA, all proteins lacking a DECH-box cysteine hydrolyzed ATP 10-15 times faster with higher K
