Investigating the Impact of Whole-Genome Duplication on Transposable Element Evolution in Teleost Fishes.
Article in Genome biology and evolution, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Transposable elements (TEs) can make up more than 50% of any given vertebrate's genome, with substantial variability in TE composition among lineages. TE variation is often linked to changes in gene regulation, genome size, and speciation. However, the role that genome duplication events have played in generating abrupt shifts in the composition of the mobilome over macroevolutionary timescales remains unclear. We investigated the degree to which the teleost genome duplication (TGD) shaped the diversification trajectory of the teleost mobilome. We integrate a new high coverage genome of Polypterus bichir with data from over 100 publicly available actinopterygian genomes to assess the macroevolutionary implications of genome duplication events on TE evolution in teleosts. Our results provide no evidence for a substantial shift in mobilome composition following the TGD event. Instead, the diversity of the teleost mobilome appears to have been shaped by a history of lineage-specific shifts in composition that are not correlated with commonly evoked drivers of diversification such as body size, water column usage, or latitude. Collectively, these results provide additional evidence for an emerging perspective that TGD did not catalyze bursts of diversification and innovation in the actinopterygian mobilome.
