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

Extended double-stranded DNA (dsRNA) duplexes can be hyper-edited by adenosine deaminases that act on RNA (ADARs). Long uninterrupted dsRNA is relatively uncommon in cells, and is frequently associated with infection by DNA or RNA viruses. Moreover, extensive adenosine to inosine editing has been reported for various viruses. A number of cellular antiviral defence strategies are stimulated by dsRNA. An additional mechanism to remove dsRNA from cells may involve hyper-editing of dsRNA by ADARs, followed by targeted cleavage. We describe here a cytoplasmic endonuclease activity that specifically cleaves hyper-edited dsRNA. Cleavage occurs at specific sites consisting of alternating IU and UI base pairs. In contrast, unmodified dsRNA and even deaminated dsRNAs that contain four consecutive IU base pairs are not cleaved. Moreover, dsRNAs in which alternating IU and UI base pairs are replaced by isomorphic GU and UG base pairs are not cleaved. Thus, the cleavage of deaminated dsRNA appears to require an RNA structure that is unique to hyper-edited RNA, providing a molecular target for the disposal of hyper-edited viral RNA.
