RNA editing status of nad7 intron domains in wheat mitochondria.
Article in Nucleic acids research, 1997. 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 most highly conserved structures of group II introns are the helical domains V and VI near the 3'splice site. Within this region of each of the four introns in the wheat mitochondrial nad7 gene encoding NADH dehydrogenase subunit 7, there are A-C mispairs. To determine whether C-to-U type RNA editing restores conventional A-U pairing, we sequenced RT-PCR products from partially-spliced nad7 template RNA and gel-fractionated, excised intron RNA. We examined transcripts from germinating wheat embryos and seedlings because these two stages of development show pronounced differences in steady state levels of nad7 intronic RNAs. We observed editing at only two of the six predicted sites, and they were located at homologous positions within domain V of the third and fourth introns. A third site was found to be edited within the unmodelled domain VI loop of the fourth intron. Similar patterns of RNA editing were seen in wheat embryos and seedlings. These observations, and the presence of other non-conventional base pairs particularly within domain V of plant mitochondrial introns, indicate weaker helical core structure than in ribozymic group II introns. Moreover, the incompleteness or absence of editing in wheat nad7 excised intron RNA suggests that, although editing may contribute to splicing efficiency, it is not essential for splicing.
