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 assembly of an orthoretrovirus such as HIV-1 requires the coordinated functioning of multiple biochemical activities of the viral Gag protein. These activities include membrane targeting, lattice formation, packaging of the RNA genome, and recruitment of cellular cofactors that modulate assembly. In most previous studies, these Gag activities have been investigated individually, which provided somewhat limited insight into how they functionally integrate during the assembly process. Here, we report the development of a biochemical reconstitution system that allowed us to investigate how Gag lattice formation, RNA binding, and the assembly cofactor inositol hexakisphosphate (IP6) synergize to generate immature virus particles
