Intrachromosomal rearrangements in avian genome evolution: evidence for regions prone to breakpoints.
Article in Heredity, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 63 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
It is generally believed that the organization of avian genomes remains highly conserved in evolution as chromosome number is constant and comparative chromosome painting demonstrated there to be very few interchromosomal rearrangements. The recent sequencing of the zebra finch (Taeniopygia guttata) genome allowed an assessment of the number of intrachromosomal rearrangements between it and the chicken (Gallus gallus) genome, revealing a surprisingly high number of intrachromosomal rearrangements. With the publication of the turkey (Meleagris gallopavo) genome it has become possible to describe intrachromosomal rearrangements between these three important avian species, gain insight into the direction of evolutionary change and assess whether breakpoint regions are reused in birds. To this end, we aligned entire chromosomes between chicken, turkey and zebra finch, identifying syntenic blocks of at least 250 kb. Potential optimal pathways of rearrangements between each of the three genomes were determined, as was a potential Galliform ancestral organization. From this, our data suggest that around one-third of chromosomal breakpoint regions may recur during avian evolution, with 10% of breakpoints apparently recurring in different lineages. This agrees with our previous hypothesis that mechanisms of genome evolution are driven by hotspots of non-allelic homologous recombination.
