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

Assembly of the enveloped hepatitis B virus (HBV) is initiated by packaging of the RNA pregenome and the viral reverse transcriptase-DNA polymerase into a nucleocapsid. The pregenome is then reverse transcribed into single-stranded minus-polarity DNA, which is subsequently replicated to double-stranded DNA. All replicative intermediates are observable in capsids within infected liver, but only relatively mature nucleocapsids containing partially double stranded DNA are found in secreted virions. This observation suggests that maturation of the genome within the capsid is required for envelopment and secretion. We show that the differential distribution of replicative intermediates between intracellular nucleocapsids and secreted virions is also observable in human hepatoma cells transfected with wild-type HBV genomes. However, nucleocapsids were not enveloped or secreted when they were produced by an HBV genome carrying a missense mutation in the DNA polymerase that eliminates all DNA synthesis. An HBV missense mutant defective in the RNase H activity of the polymerase which allowed minus-strand DNA synthesis but not formation of double-stranded DNA was able to form virion-like particles. These experiments demonstrate that immature nucleocapsids containing pregenomic RNA are incompetent for envelopment and that minus-strand DNA synthesis in the interior lumen of the capsid is coupled to the appearance of a signal on the exterior of the nucleocapsid that is essential for its envelopment.
