Methylation of LINE-1 and Alu repetitive sequence in keloid.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Keloid is a trauma-induced fibroproliferative condition characterized by excessive extracellular matrix (ECM) deposition and aberrant keloid fibroblast activation, leading to physical, psychological, functional, and cosmetic impairments. This study investigates DNA methylation alterations at Long Interspersed Nuclear Element-1 (LINE-1) and Alu repetitive elements in keloid tissues compared to normal skin tissues. Methylation levels and patterns were analyzed in keloid (n = 38) and normal skin tissues (n = 32). The results revealed significantly lower LINE-1 (P < 0.0001) and Alu (P = 0.0147) methylation levels in keloids, with hypomethylation inversely correlated with chronological age. Younger individuals exhibited higher methylation levels compared to older individuals. These findings offer critical insights into the epigenetic mechanisms underlying keloid formation and progression, providing a foundation for developing epigenetic-based therapeutic strategies.
