Complementation in cells cotransfected with a mixture of wild-type and mutant human immunodeficiency virus (HIV) influences the replication capacities and phenotypes of mutant variants in a single-cycle HIV resistance assay.
Article in Journal of clinical microbiology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The impact of cotransfection of mixtures of mutant and wild type (WT) virus on the observed phenotype and replication capacity (RC) in a single-cycle human immunodeficiency virus (HIV) phenotypic assay has been investigated by cotransfecting mutant HIV clones expressing the firefly luciferase expression gene with a WT clone expressing Renilla luciferase. Four mutant constructs with different genotypes displayed <1% RC when transfected alone. Cotransfection of as little as 9% of the WT clone resulted in an 18- to 33-fold increase in the RC of the mutant clones. In addition, the 50% inhibitory concentration (IC(50)) of lopinavir against seven mutant clones decreased by up to 97% after incremental cotransfection of 9 to 50% of the WT clone. The enhancement of RC and decrease in IC(50) for mutant variants following cotransfection with the WT variant appear to be due to complementation rather than genetic recombination. These findings suggest that the RC and susceptibility of plasma isolates from patients who are off therapy or not adherent to treatment, in which WT virus may expand to significant levels, should be interpreted with caution.
