Mapping genetic determinants of viral traits with FST and quantitative trait locus (QTL) approaches.
Article in Virology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 genetic determinism of viral traits can generally be dissected using either forward or reverse genetics because the clonal reproduction of viruses does not require the use of approaches based on laboratory crosses. Nevertheless, we hypothesized that recombinant viruses could be analyzed as sexually reproducing organisms, using either a quantitative trait loci (QTL) approach or a locus-by-locus fixation index (FST). Locus-by-locus FST analysis, and four different regressions and interval mapping algorithms of QTL analysis were applied to a phenotypic and genotypic dataset previously obtained from 47 artificial recombinant genomes generated between two begomovirus species. Both approaches assigned the determinant of within-host accumulation-previously identified using standard virology approaches-to a region including the 5׳ end of the replication-associated protein (Rep) gene and the upstream intergenic region. This study provides a proof of principle that QTL and population genetics tools can be extended to characterize the genetic determinants of viral traits.
