Splicing of the Petunia cytochrome oxidase subunit II intron.
Article in Current genetics, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
A comparative analysis of the plant intron-containing mitochondrial cytochrome oxidase subunit II (coxII) genes provides an indication that four conserved sequence motifs, present in exon 1 (intron-binding sequences; IBS), and complementary motifs (exon-binding sequences; EBS), present in domain I of the group II intron, may be involved in splicing of the intron. Two of these potential IBS motifs (IBS1 and IBS2) have been previously discussed. Two further potential IBS motifs (IBSa and IBSb), which occur twice within exon 1, could be involved in specification of the 5' splice site and of a 5' cryptic splice site. Nuclease-protection experiments and DNA sequence analysis of a spliced coxII cDNA have confirmed the predicted positions of the petunia coxII 5' and 3' splice sites. Evidence for the occurrence of splicing in vivo at the putative 5' cryptic splice site in petunia is provided by the detection of a nuclease-protected fragment corresponding to the size which is predicted if splicing at the proposed cryptic splice site occurs. The existence and location of a cryptic splice site, upstream of the normal coxII 5' splice site, is consistent with the proposed derivation of the cytoplasmic male sterility (CMS)-associated pcf gene from an abnormally spliced coxII transcript (Pruitt and Hanson 1989).
