Mitochondrial transcript length polymorphisms are a widespread phenomenon in Arabidopsis thaliana.
Article in Plant molecular biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Natural genetic variation affects development, physiology, biochemical properties as well as mitochondrial transcripts of the model species Arabidopsis thaliana (Arabidopsis). In a previous study, we identified mitochondrial transcript end polymorphisms in Arabidopsis accessions Columbia, C24 and Landsberg erecta. The polymorphic transcript species could either be assigned to differences in the mitochondrial DNA or to natural genetic variation in the nucleus. To analyze the distribution and to identify additional 5' end polymorphisms we now analyzed 19 mitochondrial transcription units in 26 different accessions. We found additional 5' end polymorphisms indicating that such transcript length differences are a widespread phenomenon in Arabidopsis. The new polymorphisms affect cox1, cox2, nad2 as well nad3-rps12 transcript species. While the cox2 polymorphism can be attributed to a recombination event in the mitochondrial DNA, the nad2 transcript polymorphism is linked to differences in the nuclear DNA. A complex pattern is found for nad3-rps12 mRNA whose 5' ends differ between several accessions. These new polymorphisms provide an important basis for a more detailed characterization of mitochondrial 5' end processing.
