trans-Complementation of HBV rtM204I mutant replication by HBV wild-type polymerase.
Article in Virology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 function of the hepatitis B virus (HBV) wild-type (WT) polymerase (pol) expressed alone or in the context of the intact genome when interacting with HBV rtM204I in HepG2 cells was compared. We show that WT pol expression from a packaging-defective RNA can complement defective rtM204I pol activity resulting in increased levels of HBV replicative intermediates (RI). Analysis of the genetically marked genomes showed that this restoration resulted from trans-complementation, rather than recombination. In contrast, we demonstrate that enhanced levels of total HBV RI observed when cells were cotransduced with both WT and rtM204I baculoviruses were predominantly WT RI. In this case, WT pol was produced from a full-length pregenomic RNA (pgRNA). We conclude that the WT pol has the capacity to trans-complement the replication defect of rtM204I; however, when expressed from an authentic pgRNA, as in a mixed infection, pol may not trans-complement efficiently.
