Primary and secondary structure analyses of the rDNA group-I introns of the Zygnematales (Charophyta).
Article in Current genetics, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 Zygnematales (Charophyta) contain a group-I intron (subgroupIC1) within their nuclear-encoded small subunit ribosomal DNA (SSU rDNA) coding region. This intron, which is inserted after position 1506 (relative to the SSU rDNA of Escherichia coli), is proposed to have been vertically inherited since the origin of the Zygnematales approximately 350-400 million years ago. Primary and secondary structure analyses were carried out to model group-I intron evolution in the Zygnematales. Secondary structure analyses support genetic data regarding sequence conservation within regions known to be functionally important for in vitro self-splicing of group-I introns. Comparisons of zygnematalean group-I intron secondary structures also provided some new insights into sequences that may have important roles in in vivo RNA splicing. Sequence analyses showed that sequence divergence rates and the nucleotide compositions of introns and coding regions within any one taxon varied widely, suggesting that the "1506" group-I introns and rDNA coding regions in the Zygnematales evolve independently.
