Origin and evolution of group I introns in cyanobacterial tRNA genes.
Article in Journal of bacteriology, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 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
Many tRNA(Leu)UAA genes from plastids contain a group I intron. An intron is also inserted in the same gene at the same position in cyanobacteria, the bacterial progenitors of plastids, suggesting an ancient bacterial origin for this intron. A group I intron has also been found in the tRNA(fMet) gene of some cyanobacteria but not in plastids, suggesting a more recent origin for this intron. In this study, we investigate the phylogenetic distributions of the two introns among cyanobacteria, from the earliest branching to the more derived species. The phylogenetic distribution of the tRNA(Leu)UAA intron follows the clustering of rRNA sequences, being either absent or present in clades of closely related species, with only one exception in the Pseudanabaena group. Our data support the notion that the tRNA(Leu)UAA intron was inherited by cyanobacteria and plastids through a common ancestor. Conversely, the tRNA(fMet) intron has a sporadic distribution, implying that many gains and losses occurred during cyanobacterial evolution. Interestingly, a phylogenetic tree inferred from intronic sequences clearly separates the different tRNA introns, suggesting that each family has its own evolutionary history.
