1 · What the graph read from it

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.

2 · The registry

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

Plant mitochondrial mRNAs have recently been shown to undergo editing, involving cytidine-to-uridine changes relative to the DNA sequence. We have examined the temporal relationship of editing and intron removal in coxII mRNAs in Petunia mitochondria. By using differential hybridization to probes specific for edited and unedited RNA and by sequencing of individual unspliced coxII pre-mRNA cDNAs, we found that RNA editing at any editing site can precede the splicing event. Similar results were obtained from examinations of pre-mRNA cDNAs of nad1, a gene composed of multiple exons that are both cis and trans spliced. Thus, intron removal is not required before editing can occur. The existence of editing intermediates indicates that the editing process is not strictly coincident with transcription.
