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 SARS-CoV-2 spike protein Q677P/H mutation and furin cleavage site (FCS) have been shown to affect cell tropism and virus transmissibility. Here, we analyzed the frequency of Q677P/H and FCS point mutations in 1,144,793 human and 1042 animal spike protein sequences and from those of the emergent variants B.1.1.7, B.1.351, P.1, B.1.429 + B.1.427, and B.1.525, which were deposited in the database of the GISAID Initiative. Different genetic polymorphisms, particularly P681H and A688V, were detected in the FCS, mainly in human isolates, and otherwise, only pangolin and bat sequences had these mutations. Multiple FCS amino acid deletions such as Δ
