Conformational dynamics of SARS-CoV-2 Omicron spike trimers during fusion activation at single molecule resolution.

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.
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
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron entry involves spike (S) glycoprotein-mediated fusion of viral and late endosomal membranes. Here, using single-molecule Förster resonance energy transfer (sm-FRET) imaging and biochemical measurements, we directly visualized conformational changes of individual spike trimers on the surface of SARS-CoV-2 Omicron pseudovirions during fusion activation. We observed that the S2 domain of the Omicron spike is a dynamic fusion machine. S2 reversibly interchanges between the pre-fusion conformation and two previously undescribed intermediate conformations. Acidic pH shifts the conformational equilibrium of S2 toward an intermediate conformation and promotes the membrane hemi-fusion reaction. Moreover, we captured conformational reversibility in the S2 domain, which suggests that spike can protect itself from pre-triggering. Furthermore, we determined that Ca
