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 2019, the severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2) started to spread globally and caused the COVID-19 pandemic. SARS-CoV-2, like other members of the Coronaviridae, has a single-stranded, positive sense RNA genome about 30 kb in length, which is translated to generate 16 non-structural proteins (NSPs); a set of sub-genomic mRNAs encode the structural and accessory proteins. The ORF1a precursor includes NSP1-11 and is processed by virus-encoded proteases to produce the mature proteins. We recently identified a short, highly conserved motif (YCPRP) within the structural protein precursor of foot-and-mouth disease virus (FMDV), a member of the Picornaviridae. This motif is conserved among picornaviruses and is found as (W/F/Y)-x-P-R-(P/A). The motif has a major influence on the processing of the FMDV capsid precursor (P1-2A) by the viral protease 3C
