Serial gene losses and foreign DNA underlie size and sequence variation in the plastid genomes of diatoms.
Article in Genome biology and evolution, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 38 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
Photosynthesis by diatoms accounts for roughly one-fifth of global primary production, but despite this, relatively little is known about their plastid genomes. We report the completely sequenced plastid genomes for eight phylogenetically diverse diatoms and show them to be variable in size, gene and foreign sequence content, and gene order. The genomes contain a core set of 122 protein-coding genes, with 15 additional genes exhibiting complex patterns of 1) gene losses at varying phylogenetic scales, 2) functional transfers to the nucleus, 3) gene duplication, divergence, and differential retention of paralogs, and 4) acquisitions of putatively functional recombinase genes from resident plasmids. The newly sequenced genomes also contain several previously unreported genes, highlighting how poorly characterized diatom plastid genomes are overall. Genome size variation reflects major expansions of the inverted repeat region in some cases but, more commonly, large-scale expansions of intergenic regions, many of which contain unique open reading frames of likely foreign origin. Although many gene clusters are conserved across species, rearrangements appear to be frequent in most lineages.
