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

Self-assembled protein capsids have gained attention as a promising class of nanoparticles for biomedical applications due to their monodisperse nature and versatile genetic and chemical tailorability. To determine the plasma clearance and tissue distribution in mice of the versatile capsid of bacteriophage Qbeta, the particles were decorated with gadolinium complexes using the CuI-mediated azide-alkyne cycloaddition reaction. Interior surface labeling was engineered by the introduction of an azide-containing unnatural amino acid into the coat protein for the first time. Clearance rates were conveniently monitored by quantitative detection of Gd using inductively coupled plasma optical emission spectroscopy and were found to be inversely proportional to the number of complexes attached to the exterior surface of the particle. This phenomenon was correlated to changes in exterior surface charge brought about by acylation of surface-exposed amine groups in the initial step of the bioconjugation protocol. When primary amine groups were reintroduced by azide-alkyne coupling, the circulation time increased accordingly. These results show that nanoparticle trafficking may be tailored in predictable ways by chemical and genetic modifications that modulate surface charge.
