Molecular population genetics of the Arabidopsis CLAVATA2 region. The genomic scale of variation and selection in a selfing species.
Article in Genetics, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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 CLAVATA2 (CLV2) gene encodes a leucine-rich repeat protein that regulates the development of the shoot meristem. The levels and patterns of nucleotide variation were assessed for CLV2 and 10 flanking genes that together span a 40-kb region of chromosome I. A total of 296 out of 7959 sequenced nucleotide sites were polymorphic. The mean levels of sequence diversity of the contiguous genes in this region are approximately twofold higher than those of other typical Arabidopsis nuclear loci. There is, however, wide variation in the levels and patterns of sequence variation among the 11 linked genes in this region, and adjacent genes appear to be subject to contrasting evolutionary forces. CLV2 has the highest levels of nucleotide variation in this region, a significant excess of intermediate frequency polymorphisms, and significant levels of intragenic linkage disequilibrium. Most alleles at CLV2 are found in one of three haplotype groups of moderate (>15%) frequency. These features suggest that CLV2 may harbor a balanced polymorphism.
