WRKY gene family evolution in Arabidopsis thaliana.
Article in Genetica, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 66 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 Arabidopsis thaliana WRKY proteins are characterized by a sequence of 60 amino acids including WRKY domain. It is well established that these proteins are involved in the regulation of various physiological programs unique to plants including pathogen defense, senescence and response to environmental stresses, which attracts attention of the scientific community as to how this family might have evolved. We tried to satisfy this curiosity and analyze reasons for duplications of these gene sequences leading to their diversified gene actions. The WRKY sequences available in Arabidopsis thaliana were used to evaluate selection pressure following duplication events. A phylogenetic tree was constructed and the WRKY family was divided into five sub-families. After that, tests were conducted to decide whether positive or purified selection played key role in these events. Our results suggest that purifying selection played major role during the evolution of this family. Some amino acid changes were also detected in specific branches of phylogeny suggesting that relaxed constraints might also have contributed to functional divergence among sub-families. Sites relaxed from purifying selection were identified and mapped onto the structural and functional regions of the WRKY1 protein. These analyses will enhance our understanding of the precise role played by natural selection to create functional diversity in WRKY family.
