Loss of all ndh genes as determined by sequencing the entire chloroplast genome of the black pine Pinus thunbergii.
Article in Proceedings of the National Academy of Sciences of the United States of America, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 183 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
The complete nucleotide sequence (119,707 bp) of the black pine (Pinus thunbergii) chloroplast genome has been determined. It contains 4 rRNA genes and 32 tRNA genes. To our knowledge, the tRNAPro (GGG) gene has not been found in any other chloroplast genome analyzed. Sixty-one genes encoding proteins and 11 conserved open reading frames are also found. Extensive rearrangements are apparent in the chloroplast genome relative to those of other land plants. The most striking feature is the loss of all 11 functional genes (ndh genes) for subunits of a putative NADH dehydrogenase that are found in the chloroplast genomes of angiosperms and a bryophyte. Four ndh genes were completely lost and the other 7 genes remain as obvious pseudogenes. This unexpected finding raises the possibility that all ndh genes have been transferred to the nucleus or that an NADH dehydrogenase is not essential in black pine chloroplasts.
