SINE-derived satellites in scaled reptiles.
Article in Mobile DNA, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThe genomes of many eukaryotes contain DNA repeats in the form of both tandem and interspersed elements with distinct structure, evolutionary histories, and mechanisms of emergence and amplification. Although there is considerable knowledge regarding their diversity, there is little evidence directly linking these two types.
resultsDifferent tandem repeats derived from portions of short interspersed elements (SINEs) belonging to different families were identified in 56 genomes of squamate reptiles. All loci of SINE-derived satellites (sSats) were thoroughly analyzed. Snake sSats exhibited high similarity in both structure and copy number, while other taxa may have highly diverse (geckos), rare (Darevskia lizards), or missing sSats (agamid lizards). Similar to most satellites associated with heterochromatin, sSats are likely linked to subtelomeric chromosomal regions.
conclusionsDiscovered tandem repeats derived from SINEs exhibit satellite-like properties, although they have not amplified to the same degree as typical satellites. The autonomous emergence of distinct sSats from diverse SINE families in numerous squamate species suggests a nonrandom process of satellite genesis originating from repetitive SINEs.
