Lepidopteran Synteny Units reveal deep chromosomal conservation in butterflies and moths.
Article in G3 (Bethesda, Md.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
DNA is compacted into individual particles or chromosomes that form the basic units of inheritance. However, different animals and plants have widely different numbers of chromosomes. This means that we cannot readily tell which chromosomes are related to which. Here, we describe a simple technique that looks at the similarity of genes on each chromosome and thus gives us a true picture of their homology or similarity through evolutionary time. We use this new system to look at the chromosomes of butterflies and moths or Lepidoptera. We term the associated synteny units, Lepidopteran Synteny Units (LSUs). Using a sample of butterfly and moth genomes from across evolutionary time, we show that LSUs form a simple and reliable method of tracing chromosomal homology back through time. Surprisingly, this technique reveals that butterfly and moth chromosomes show conserved blocks dating back to their sister group the Trichoptera. As Lepidoptera have holocentric chromosomes, it will be interesting to see if similar levels of synteny are shown in groups of animals with monocentric chromosomes. The ability to define homology via LSU analysis makes it considerably easier to approach many questions in chromosomal evolution.
