Protein determinants of insertional specificity for the Drosophila gypsy retrovirus.
Article in Genetics, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 gypsy retrovirus invades the germ line of Drosophila females, inserting with a high frequency into the ovo locus. Gypsy insertion sites in ovo are clustered within a region in the promoter of the ovo gene that contains multiple binding sites for the OvoA and OvoB proteins. We found that a 1.3-kb DNA fragment containing this region is able to confer gypsy insertional specificity independent of its genomic location. The frequency of gypsy insertions into the ovo gene is significantly lower in wild-type females than in ovoD1 females. In addition, gypsy insertions in ovoD1 females occur during most stages of germ-line development whereas insertions in wild-type females occur only in late stages. This pattern of temporally specific insertions, as well as the higher frequency of insertion in ovoD1 females, correlates with the presence of the OvoA or OvoD1 proteins. The results suggest that gypsy insertional specificity might be determined by the binding of the OvoA repressor isoform to the promoter region of the gene.
