Multilocus analysis of variation and speciation in the closely related species Arabidopsis halleri and A. lyrata.
Article in Genetics, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 54 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
Nucleotide variation in eight effectively unlinked genes was surveyed in species-wide samples of the closely related outbreeding species Arabidopsis halleri and A. lyrata ssp. petraea and in three of these genes in A. lyrata ssp. lyrata and A. thaliana. Significant genetic differentiation was observed more frequently in A. l. petraea than in A. halleri. Average estimates of nucleotide variation were highest in A. l. petraea and lowest in A. l. lyrata, reflecting differences among species in effective population size. The low level of variation in A. l. lyrata is concordant with a bottleneck effect associated with its origin. The A. halleri/A. l. petraea speciation process was studied, considering the orthologous sequences of an outgroup species (A. thaliana). The high number of ancestral mutations relative to exclusive polymorphisms detected in A. halleri and A. l. petraea, the significant results of the multilocus Fay and Wu H tests, and haplotype sharing between the species indicate introgression subsequent to speciation. Average among-population variation in A. halleri and A. l. petraea was approximately 1.5- and 3-fold higher than that in the inbreeder A. thaliana. The detected reduction of variation in A. thaliana is less than that expected from differences in mating system alone, and therefore from selective processes related to differences in the effective recombination rate, but could be explained by differences in population structure.
