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

Rotaviruses (RVs) induce the formation of cytoplasmic viral factories, termed viroplasms, which are the sites of early particle assembly and viral RNA synthesis. The RV octameric nonstructural protein 2 (NSP2) plays critical, albeit incompletely understood, roles during viroplasm biogenesis. Previous work by our lab demonstrated that a RV bearing a lysine-to-glutamic acid (K294E) change in the flexible C-terminus of NSP2 exhibits defects in viral replication and induces smaller, more numerous viroplasms as compared to the wildtype (WT) virus. In this study, we sought to better understand if/how this K294E amino acid change altered the structure and/or dynamics of the NSP2 protein. We first determined the X-ray crystal structures of untagged, recombinant NSP2
