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 Hepatitis B Virus (HBV) core protein homodimers self-assemble to form an icosahedral capsid that packages the viral genome. Disassembly occurs in the nuclear basket to release the mature genome to the nucleus. Small molecules have been developed that bind to a pocket at the interdimer interface to accelerate assembly and strengthen interactions between subunits; these are under development as antiviral agents. Here, we explore the role of the dimer-dimer interface by mutating sites in the drug-binding pocket to cysteine and examining the effect of covalently linking small molecules to them. We find that ligands bound to the pocket may trigger capsid disassembly in a dose-dependent manner. This result indicates that, at least transiently, the pocket adopts a destabilizing conformation. We speculate that this pocket also plays a role in virus disassembly and genome release by binding ligands that are incompatible with virus stability, "unwanted guests." Investigating protein-protein interactions, especially large protein polymers, offers new and unique challenges. By using an engineered addressable thiol, we provide a means to examine the effects of modifying an interface without requiring drug-like properties for the ligand.
