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 rapid evolution of SARS-CoV-2 variants, driven by antigenic drift in the spike glycoprotein, continues to undermine the efficacy of current vaccines and monoclonal antibody therapies. Targeting conserved features of the spike protein has been a major focus against coronavirus entry and the development of therapeutics. Here, we demonstrate that the plant lectin concanavalin A (ConA) broadly inhibits coronavirus entry through a conserved mechanism. With a combination of cell-cell fusion, pseudoviral entry, and authentic virus infection models, we show that ConA broadly inhibits coronavirus spike-mediated membrane fusion and viral entry. Biochemical analyses reveal that ConA targets two highly conserved N-glycosylation sites outside the receptor binding domain, flanking the S2' cleavage site via its mannose-binding properties. This interaction sterically impedes proteolytic activation of the spike, a molecular step essential for membrane fusion. ConA exhibited nanomolar efficacy against hCoV-NL63 infections
