The horsetail Equisetum arvense mitochondria share two group I introns with the liverwort Marchantia, acquired a novel group II intron but lost intron-encoded ORFs.

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
We studied the genomic structure and RNA editing of mitochondrial cox1, cox2, cob and atp9 from the horsetail Equisetum arvense, a representative of an old fern lineage. Editing of cox1, cob and atp9 mRNAs occur only by C-to-U transitions. No changes were found in cox2 transcripts constituting one of the rare examples of unedited mitochondrial mRNA in land plants. From three intervening sequences in cox1, cox1i395 and cox1i624 are group IB introns homologous to the Marchantia polymorpha cox1 introns, and cox1i747 is a group IIA intron different to other introns found in plant mtDNA. The group II intron cox2i373 is very similar to other introns found in cox2 from vascular plants. While cob and atp9 have no introns and display the gene structure found in seed plants, various nucleotide substitutions abolish the only potential ORF, a LAGLIDADG endonuclease present in cox1i395. Thus, E. arvense mitochondria conserve two group I introns from non-vascular plants, probably inherited from a common ancestor with liverworts. Analogous to seed plants, E. arvense has no potential mitochondrial splicing factors encoded in these introns. This is the first report concerning the presence of vertically inherited group I introns in vascular plant mitochondria.
