Empoasca leafhoppers attack wild tobacco plants in a jasmonate-dependent manner and identify jasmonate mutants in natural populations.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 53 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
Choice of host plants by phytophagous insects is essential for their survival and reproduction. This choice involves complex behavioral responses to a variety of physical and chemical characteristics of potential plants for feeding. For insects of the order Hemiptera, these behavioral responses involve a series of steps including labial dabbing and probing using their piercing mouthparts. These initial probing and feeding attempts also elicit a rapid accumulation of phytohormones, such as jasmonic acid (JA), and the induced defense metabolites they mediate. When Nicotiana attenuata plants are rendered JA deficient by silencing the initial committed step of the JA biosynthesis pathway, they are severely attacked in nature by hemipteran leafhoppers of the genus Empoasca. By producing N. attenuata plants silenced in multiple steps of JA biosynthesis and perception and in the biosynthesis of the plant's three major classes of JA-inducible insecticidal defenses, we demonstrate that the choice of plants for feeding by Empoasca leafhoppers in both nature and the glasshouse is independent of the accumulation of major insecticidal molecules. Moreover, this choice is independent of the presence of Candidatus Phytoplasma spp. and is not associated with detectable changes in plant volatiles but instead depends on the plant's capacity to mediate JA signaling. We exploited this trait and used Empoasca leafhoppers to reveal genetic variation in JA accumulation and signaling hidden in N. attenuata natural populations.
