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

The innermost VP2 core shell of the triple-layered, icosahedral rotavirus particle surrounds the viral genome and RNA processing enzymes, including the RNA-dependent RNA polymerase (VP1). In addition to anchoring VP1 within the core, VP2 is also an essential cofactor that triggers the polymerase to initiate double-stranded RNA (dsRNA) synthesis using packaged plus-strand RNA templates. The VP2 requirement effectively couples packaging with genome replication and ensures that VP1 makes dsRNA only within an assembling previrion particle. However, the mechanism by which the rotavirus core shell protein activates the viral polymerase remains very poorly understood. In the current study, we sought to elucidate VP2 regions critical for VP1-mediated in vitro dsRNA synthesis. By comparing the functions of proteins from several different rotaviruses, we found that polymerase activation by the core shell protein is specific. Through truncation and chimera mutagenesis, we demonstrate that the VP2 amino terminus, which forms a decameric, internal hub underneath each 5-fold axis, plays an important but nonspecific role in VP1 activation. Our results indicate that the VP2 residues correlating with polymerase activation specificity are located on the inner face of the core shell, distinct from the amino terminus. Based on these findings, we predict that several regions of VP2 engage the polymerase during the concerted processes of rotavirus core assembly and genome replication.
