Evolution of six novel ORFs in the plastome of Mankyua chejuense and phylogeny of eusporangiate ferns.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
In this paper, three plastomes of Mankyua chejuense, Helminthostachys zeylanica, and Botrychium ternatum in Ophioglossaceae were completely sequenced in order to investigate the plastome evolution and phylogeny of eusporangiate ferns. They were similar to each other in terms of length and the gene orders; however, six unknown open reading frames (ORFs) were found between rps4 and trnL-UAA genes in M. chejuense. Similar sequence regions of six ORFs of M. chejuense were found at the plastomes of Ophioglossum californicum and H. zeylanica, as well as the mitochondrial genome (mitogenome) of H. zeylanica, but not in B. ternatum. Interestingly, the translated amino acid sequences of three ORFs were more similar to the proteins of distantly related taxa such as algae and bacteria than they were to proteins in land plants. It is likely that the six ORFs region arose from endosymbiotic gene transfer (EGT) or horizontal gene transfer (HGT), but further study is needed to verify this. Phylogenetic analyses suggested that Mankyua was resolved as the earliest diverging lineage and that Ophioglossum was subsequently diverged in Ophioglossaceae. This result supports why the plastome of M. chejuense have contained the most ancestral six ORFs in the family.
