Independent degradation in genes of the plastid ndh gene family in species of the orchid genus Cymbidium (Orchidaceae; Epidendroideae).
Article in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 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, we compare ndh genes in the plastid genome of many Cymbidium species and three closely related taxa in Orchidaceae looking for evidence of ndh gene degradation. Among the 11 ndh genes, there were frequently large deletions in directly repeated or AT-rich regions. Variation in these degraded ndh genes occurs between individual plants, apparently at population levels in these Cymbidium species. It is likely that ndh gene transfers from the plastome to mitochondrial genome (chondriome) occurred independently in Orchidaceae and that ndh genes in the chondriome were also relatively recently transferred between distantly related species in Orchidaceae. Four variants of the ycf1-rpl32 region, which normally includes the ndhF genes in the plastome, were identified, and some Cymbidium species contained at least two copies of that region in their organellar genomes. The four ycf1-rpl32 variants seem to have a clear pattern of close relationships. Patterns of ndh degradation between closely related taxa and translocation of ndh genes to the chondriome in Cymbidium suggest that there have been multiple bidirectional intracellular gene transfers between two organellar genomes, which have produced different levels of ndh gene degradation among even closely related species.
