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

Coronaviridae spike glycoproteins mediate viral entry and fusion to host cells through binding to host receptors (i.e., ACE2, DPP4) and are key components in determining viral host range, making them targets for antiviral research. Here, we describe the expression, purification, and characterization of recombinant spike proteins to aid in protein characterization and analysis. These protocols were used for the production of spike glycoproteins from civet, pangolin, and bat coronaviruses, as well as high-resolution cryo-electron microscopy (cryo-EM) structural analysis of bat and civet host coronavirus spike glycoproteins (Hills et al., 2024). © 2025 The Author(s). Current Protocols published by Wiley Periodicals LLC. Basic Protocol 1: Expression and purification of SARS-CoV spike protein from ExpiCHO cells Basic Protocol 2: Preparation of SARS-CoV spike protein for visualization by negative-stain transmission electron microscopy and cryo-electron microscopy.
