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

Accurate mass analysis can provide useful information on the stoichiometry and composition of protein-based particles, such as virus-like assemblies. For applications in nanotechnology and medicine, such nanoparticles are loaded with foreign cargos, making accurate mass information essential to define the cargo load. Here, we describe modifications to an Orbitrap mass spectrometer that enable high mass analysis of several virus-like nanoparticles up to 4.5 MDa in mass. This allows the accurate determination of the composition of virus-like particles. The modified instrument is utilized to determine the cargo load of bacterial encapsulin nanoparticles that were engineered to encapsulate foreign cargo proteins. We find that encapsulin packages from 8 up to 12 cargo proteins, thereby quantifying cargo load but also showing the ensemble spread. In addition, we determined the previously unknown stoichiometry of the three different splice variants of the capsid protein in adeno-associated virus (AAV) capsids, showing that symmetry is broken and assembly is heterogeneous and stochastic. These results demonstrate the potential of high-resolution mass analysis of protein-based nanoparticles, with widespread applications in chemical biology and nanotechnology.
