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 abundant, liver-specific microRNA miR-122 forms extensive base-pairing interactions with the 5' noncoding region of the hepatitis C virus (HCV) RNA genome, protecting the viral RNA from degradation. We discovered that the 5'-3' exoribonuclease Xrn2, which plays a crucial role in the transcription termination of RNA polymerase II, modulates HCV RNA abundance in the cytoplasm, but is counteracted by miR-122-mediated protection. Specifically, Xrn2 depletion results in increased accumulation of viral RNA, while Xrn2 overexpression diminishes viral RNA abundance. Depletion of Xrn2 did not alter translation or replication rates of HCV RNA, but affected viral RNA stability. Importantly, during sequestration of miR-122, Xrn2 depletion restored HCV RNA abundance, arguing that Xrn2 depletion eliminates the miR-122 requirement for viral RNA stability. Thus, Xrn2 has a cytoplasmic, antiviral function against HCV that is counteracted by HCV's subversion of miR-122 to form a protective oligomeric complex at the 5' end of the viral genome.
