Lateral transfer of introns in the cryptophyte plastid genome.
Article in Nucleic acids research, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Cryptophytes are unicellular eukaryotic algae that acquired photosynthesis secondarily through the uptake and retention of a red-algal endosymbiont. The plastid genome of the cryptophyte Rhodomonas salina CCMP1319 was recently sequenced and found to contain a genetic element similar to a group II intron. Here, we explore the distribution, structure and function of group II introns in the plastid genomes of distantly and closely related cryptophytes. The predicted secondary structures of six introns contained in three different genes were examined and found to be generally similar to group II introns but unusually large in size (including the largest known noncoding intron). Phylogenetic analysis suggests that the cryptophyte group II introns were acquired via lateral gene transfer (LGT) from a euglenid-like species. Unexpectedly, the six introns occupy five distinct genomic locations, suggesting multiple LGT events or recent transposition (or both). Combined with structural considerations, RT-PCR experiments suggest that the transferred introns are degenerate 'twintrons' (i.e. nested group II/group III introns) in which the internal intron has lost its splicing capability, resulting in an amalgamation with the outer intron.
