Adaptive evolution of crustin antimicrobial peptides in decapods.
Article in Genetica, 2012. 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
Antimicrobial peptides (AMPs) are present in a wide range of taxonomic groups and played a crucial role in host adaptation to a diverse array of ever-changing pathogens. Crustin, a cysteine-rich cationic AMP, is known to exhibit antimicrobial activity against Gram-positive and Gram-negative bacteria in decapods. Given their important role in host-immune defense, a large proportion of amino acid substitutions in crustin AMPs are expected to be fixed by natural selection. Utilizing the complete coding nucleotide sequence data of crustin, the present study revealed the pervasive role of positive Darwinian selection in the evolution and divergence of crustin AMPs in decapods. Approximately, 20-35 % of codons in two phylogenetically distinct groups of closely related crustins in Penaeid shrimps are shown to have evolved under positive selection. Interestingly, several of these positively selected sites are located at the carboxyl-terminal region, the region that directly interacts with the invading pathogens. Pathogen-mediated selection pressure could be the likely cause for such an accelerated rate of amino acid substitutions and could have contributed to the structural and functional diversification of crustin AMPs in several taxa.
