In vivo expression of a new hepatitis B virus protein encoded by a spliced RNA.
Article in The Journal of clinical investigation, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 55 papers.
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
Hepatitis B virus (HBV) is a small DNA virus with a compact genomic organization. All HBV proteins identified to date have been encoded by unspliced HBV RNAs. Spliced HBV RNAs have been described, but their functions are unknown. We show here that a singly spliced HBV RNA encodes a novel HBV protein in vivo. This HBV splice-generated protein (HBSP) corresponds to the fusion of a part of the viral polymerase and a new open reading frame that is created by the splicing event. In vivo, HBSP protein was found in HBV-infected liver samples, and anti-HBSP antibodies occurred in one-third of sera samples collected from chronic HBV carriers. In vitro, the ectopic expression of HBSP had no effect on viral DNA replication or transcription but induced cell apoptosis without a cell-cycle block. Overall, our results suggest that HBV has evolved a mechanism that directly modulates virus-cell interaction through RNA splicing.
