Differential RNA editing in closely related introns in Oenothera mitochondria.

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
Introns a/b of the nad2 gene and b/c of the nad1 gene in Oenothera mitochondria were found to be closely related. Within a scaffold of conserved sequence regions, a 48 bp sequence element covering intron domain V and flanking nucleotides is identical in both group II introns. The third nucleotide of this element is edited in the nad2, but not in the nad1 intervening sequence. The C to U editing event compensates an nad2-specific nucleotide mismatch in the stem domain IV and thus improves secondary structure stability. This differential editing event indicates that the identical upstream 2 and downstream 45 nucleotides are not sufficient to specify this editing site. Comparison of adjacent exon editing patterns in spliced and unspliced transcripts shows a higher degree of editing in processed sequences, confirming that RNA editing is a posttranscriptional process in plant mitochondria.
