Vertebrate attenuated West Nile virus mutants have differing effects on vector competence in Culex tarsalis mosquitoes.
Article in The Journal of general virology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Previous mutational analyses of naturally occurring West Nile virus (WNV) strains and engineered mutant WNV strains have identified locations in the viral genome that can have profound phenotypic effect on viral infectivity, temperature sensitivity and neuroinvasiveness. We chose six mutant WNV strains to evaluate for vector competence in the natural WNV vector Culex tarsalis, two of which contain multiple ablations of glycosylation sites in the envelope and NS1 proteins; three of which contain mutations in the NS4B protein and an attenuated natural bird isolate (Bird 1153) harbouring an NS4B mutation. Despite vertebrate attenuation, all NS4B mutant viruses displayed enhanced vector competence by Cx. tarsalis. Non-glycosylated mutant viruses displayed decreased vector competence in Cx. tarsalis mosquitoes, particularly when all three NS1 glycosylation sites were abolished. These results indicate the importance of both the NS4B protein and NS1 glycosylation in the transmission of WNV by a significant mosquito vector.
