Identification of an Intermediate in Hepatitis B Virus Covalently Closed Circular (CCC) DNA Formation and Sensitive and Selective CCC DNA Detection.
Article in Journal of virology, 2017. 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) covalently closed circular (CCC) DNA functions as the only viral template capable of coding for all the viral RNA species and is thus essential to initiate and sustain viral replication. CCC DNA is converted, in a multistep and ill-understood process, from a relaxed circular (RC) DNA, in which neither of the two DNA strands is covalently closed. To detect putative intermediates during RC DNA to CCC DNA conversion, two 3' exonucleases, exonuclease I (Exo I) and Exo III, were used in combination to degrade all DNA strands with a free 3' end, which would nevertheless preserve closed circular DNA in either single-stranded (SS) or double-stranded (DS) form. Indeed, an RC DNA species with a covalently closed minus strand but an open plus strand (closed minus-strand RC DNA [cM-RC DNA]) was detected by this approach. Further analyses indicated that at least some of the plus strands in such a putative intermediate likely still retained the RNA primer that is attached to the 5' end of the plus strand in RC DNA, suggesting that minus-strand closing can occur before plus-strand processing. Furthermore, the same nuclease treatment proved to be useful for sensitive and specific detection of CCC DNA by removing all DNA species other than closed circular DNA. Application of these and similar approaches may allow the identification of additional intermediates during CCC DNA formation and facilitate specific and sensitive detection of CCC DNA, which should help elucidate the pathways of CCC DNA formation and the factors involved.
