Ribosomal Intergenic Spacers Are Filled with Transposon Remnants.
Article in Genome biology and evolution, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Eukaryotic ribosomal DNA (rDNA) comprises tandem units of highly conserved coding genes separated by rapidly evolving spacer DNA. The spacers of all 12 species examined were filled with short direct repeats (DRs) and multiple long tandem repeats (TRs), completing the rDNA maps that previously contained unannotated and inadequately studied sequences. The external transcribed spacers also were filled with DRs and some contained TRs. We infer that the spacers arose from transposon insertion, followed by their imprecise excision, leaving short DRs characteristic of transposon visitation. The spacers provided a favored location for transposon insertion because they occupy loci containing hundreds to thousands of gene repeats. The spacers' primary cellular function may be to link one ribosomal RNA transcription unit to the next, whereas transposons flourish here because they have colonized the most frequently used part of the genome.
