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

Circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the human population leads to further viral evolution. The new variants that arise during this evolution are more infectious. Our data suggest that newer variants have shifted from utilizing both cathepsin/endosome- and TMPRSS2-mediated entry mechanisms to rely on a TMPRSS2-dependent entry pathway. Accordingly, only the early lineages of SARS-CoV-2 are capable of infecting and forming syncytia in Vero/ACE2 cells which lack TMPRSS2 expression. The presence of an intact multibasic furin cleavage site (FCS) in the S protein was a key requirement for cell-to-cell fusion. Deletion of FCS makes SARS-CoV-2 more infectious
