In vivo transmission and dynamics of deleted genomes after experimental infection of woodchuck hepatitis B virus in adult animals.

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.
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 presence of Deleted Genomes has been shown in a number of viral models including Hepadnaviridae. The analysis of woodchuck hepatitis B virus (WHV) population after experimental infection of woodchuck 197 (W197) with WHV7-PI inoculum revealed the presence of two Deleted Genomes: DG600 lacking a 1330 bp region (Core/Polymerase/PreS1) and DG900 showing a deletion of 869 nts (Pol/PreS/S). These mutants were also present in WHV7-PI. The successive WHV experimental infections in adult animals were performed using W197-w7 inoculum containing DG600 and DG900. Infections were divided into three groups presenting different patterns of viral replication, different presence of markers, occurrence of variants and persistence of infection. The first group displayed 2-3 weeks viremic phase and WHV-DNA titres of 10-30 ng/ml; the second a longer viremic phase (8-9 weeks) and higher WHV-DNA titres (up to 78 ng/ml). In contrast, the third group exhibited lifetime presence of WHV-DNA and WHVeAg in serum and viral replication in liver. The Deleted Genomes were transmitted in the newly infected animals with the same genomic organization. DG600 was persistently found only in chronically infected woodchuck, whereas a different pattern of presence was described for DG900. The characterization of these classes of deleted mutants in woodchuck-WHV model raises new questions on the link between DGs and persistent infections.
