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

In a negative-strand RNA virus, the genomic RNA is sequestered inside the nucleocapsid when the viral RNA-dependent RNA polymerase uses it as the template for viral RNA synthesis. It must require a conformational change in the nucleocapsid protein (N) to make the RNA accessible to the viral polymerase during this process. The structure of an empty mumps virus (MuV) nucleocapsid-like particle was determined to 10.4-Å resolution by cryo-electron microscopy (cryo-EM) image reconstruction. By modeling the crystal structure of parainfluenza virus 5 into the density, it was shown that the α-helix close to the RNA became flexible when RNA was removed. Point mutations in this helix resulted in loss of polymerase activities. Since the core of N is rigid in the nucleocapsid, we suggest that interactions between this region of the mumps virus N and its polymerase, instead of large N domain rotations, lead to exposure of the sequestered genomic RNA.
