Population structure and its effects on patterns of nucleotide polymorphism in teosinte (Zea mays ssp. parviglumis).
Article in Genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Surveys of nucleotide diversity in the wild ancestor of maize, Zea mays ssp. parviglumis, have revealed genomewide departures from the standard neutral equilibrium (NE) model. Here we investigate the degree to which population structure may account for the excess of rare polymorphisms frequently observed in species-wide samples. On the basis of sequence data from five nuclear and two chloroplast loci, we found significant population genetic structure among seven subpopulations from two geographic regions. Comparisons of estimates of population genetic parameters from species-wide samples and subpopulation-specific samples showed that population genetic subdivision influenced observed patterns of nucleotide polymorphism. In particular, Tajima's D was significantly higher (closer to zero) in subpopulation-specific samples relative to species-wide samples, and therefore more closely corresponded to NE expectations. In spite of these overall patterns, the extent to which levels and patterns of polymorphism within subpopulations differed from species-wide samples and NE expectations depended strongly on the geographic region (Jalisco vs. Balsas) from which subpopulations were sampled. This may be due to the demographic history of subpopulations in those regions. Overall, these results suggest that explicitly accounting for population structure may be important for studies examining the genetic basis of ecologically and agronomically important traits as well as for identifying loci that have been the targets of selection.
