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

Coronavirus infections are a world-wide threat to human health. A promising strategy to develop a broadly active antiviral is the use of fusion proteins consisting of an antibody IgG Fc region and a human ACE2 domain to which the viral spike proteins bind. Here we create antiviral fusion proteins based on IgM scaffolds. The hexameric ACE2-IgM-Fc fusions can be efficiently produced in mammalian cells and they neutralize the infectious virus with picomolar affinity thus surpassing monomeric ACE2-IgM-Fc by up to 96-fold in potency. In addition, the ACE2-IgM fusion shows increased neutralization efficiency for the highly infectious SARS-CoV-2 omicron variant in comparison to prototypic SARS-CoV-2. Taken together, these multimeric IgM fusions proteins are a powerful weapon to fight coronavirus infections.
