SARS-CoV-2 NSP1 induces mRNA cleavages on the ribosome.

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.
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 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the non-structural protein NSP1 inhibits translation of host mRNAs by binding to the mRNA entry channel of the ribosome and, together with the 5'-untranslated region (UTR) of the viral mRNAs, allows the evasion of that inhibition. Here, we show that NSP1 mediates endonucleolytic cleavages of both host and viral mRNAs in the 5'UTR, but with different cleavage patterns. The first pattern is observed in host mRNAs with cleavages interspersed regularly and close to the 5' cap (6-11 nt downstream of the cap). Those cleavage positions depend more on the position relative to the 5' cap than on the sequence itself. The second cleavage pattern occurs at high NSP1 concentrations and only in SARS-CoV-2 RNAs, with the cleavages clustered at positions 45, 46 and 49. Both patterns of cleavage occur with the mRNA and NSP1 bound to the ribosome, with the SL1 hairpin at the 5' end sufficient to protect from NSP1-mediated degradation at low NSP1 concentrations. We show further that the N-terminal domain of NSP1 is necessary and sufficient for efficient cleavage. We suggest that in the ribosome-bound NSP1 protein the catalytic residues of the N-terminal domain are unmasked by the remodelling of the α1- and α2-helices of the C-terminal domain.
