Evolution of the mitochondrial genome in cephalochordata as inferred from complete nucleotide sequences from two epigonichthys species.
Article in Journal of molecular evolution, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 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
Complete mitochondrial (mt) DNA sequences of two lancelets, Epigonichthys maldivensis and E. lucayanus, were compared with those of two Branchiostoma lancelets and several deuterostomes previously surveyed. The mt-gene order of E. lucayanus was quite different from that of E. maldivensis, the latter being identical to the two Branchiostoma species. A remarkable genomic change in E. lucayanus mtDNA was an inversion, indicating the possibility of recombination of the mt-genome. Gene rearrangements, probably attributable to tandem genome duplications and subsequent random deletions, were observed in two parts. Short major unassignable sequences of the examined lancelets were regarded as a part of putative regulative elements, judging from some sequence similarity to the conserved sequence block (CSB) in mammalian mtDNA. The considerable mt-genome reorganization in E. lucayanus seemed to have affected the nucleotide substitution pattern, suggested by base composition analyses. The present analysis also suggested that AGR codons in lancelet mtDNA were likely to correspond to serine residue, rather than glycine. Furthermore, the AGG codon, so far reputed to be unassignable in lancelet mtDNA, was found twice in E. maldivensis, indicating the availability of all four AGN codons in some lancelets. This finding lends support to an alternative hypothesis regarding the evolutionary history of AGR-codon assignment in extant chordates, rather than that previously proposed. A molecular phylogenetic tree of the Epigonichthys and Branchiostoma species based on DNA sequences of the 13 mt-protein genes doubted the monophyly of the former genus, unlike the prevailing classification based on their different gonadal arrangements.
