Genetic Structure of the Aphis craccivora (Hemiptera: Aphididae) From Thailand Inferred From Mitochondrial COI Gene Sequence.
Article in Journal of insect science (Online), 2017. 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 cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae), is one of the most destructive insect pests of legume plants worldwide. Although outbreaks of this pest occur annually in Thailand causing heavy damage, its genetic structure and demographic history are poorly understood. In order to determine genetic structure and genetic relationship of the geographic populations of this species, we examined sequences of mitochondrial cytochrome c oxidase subunit I (COI) gene of 51 individuals collected from 32 localities throughout Thailand. Within the sequences of these geographic populations, 32 polymorphic sites defined 17 haplotypes, ranging in sequence divergence from 0.2% (1 nucleotide) to 2.7% (16 nucleotides). A relatively high haplotype diversity but low nucleotide diversity was detected in the populations of A. craccivora, a finding that is typical for migratory species. Phylogenetic analysis revealed a weak phylogeographic structuring among the geographic populations and among the haplotypes, indicating their close relationship. Considering the distance between the sampling sites, the occurrence of identical haplotypes over wide areas is noteworthy. Moreover, the low genetic distance (FST ranging from -0.0460 to 0.3263) and high rate of per-generation female migration (Nm ranging from 1.0323 to 20.3333) suggested population exchange and gene flow between the A. craccivora populations in Thailand.
