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

mRNA-processing bodies (P bodies) are cytoplasmic foci that contain translationally repressed mRNA. Since they are important for the retrotransposition of Ty elements and brome mosaic virus in yeast cells, we assessed the role of P bodies in the movement of endogenous intracisternal A particles (IAPs) in mammalian cells. In contrast to the case for these other systems, their disruption via knockdown of RCK or eukaryotic initiation factor E transporter (eIF4E-T) increased IAP retrotransposition as well as levels of IAP transcripts, Gag proteins, and reverse transcription products. This increase was not mediated by impairing the microRNA pathway. Rather, the removal of P bodies shifted IAP mRNA from nonpolysomal to polysomal fractions. Although IAP mRNA localized to P bodies, Gag was targeted to the endoplasmic reticulum (ER), from which IAP buds. Thus, by sequestering IAP mRNA away from Gag, P bodies inhibit rather than promote IAP retrotransposition.
