Genome-wide DNA methylation profiles and ribosomal DNA copy number at birth.

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
Ribosomal DNA copy number (rDNAcn) and DNA methylation are important modulators of the human genome, both studied in relation to overall cellular function, biological ageing, and disease development. Despite the overlapping roles, their relationship remains poorly understood, especially in the early stages of life, characterized by rapid growth and high cellular demands. Even though previous studies have associated rDNA methylation with cancer and ageing, no study to date has examined the interplay between rDNAcn and whole-genome DNA methylation. In an epigenome-wide association study of 45S rDNAcn variation in 194 newborns, we show strong positive associations between rDNAcn and single DNA methylated CpGs, measured with the Illumina EPIC array. Out of the 122 Bonferroni-significant CpGs, 63.5% were also Bonferroni-significant in a replication cohort of 167 newborns, in which a second EWAS was conducted using DNA methylation data from the Illumina 450K array. The identified CpGs were dispersed over the autosomes and were not functionally related to the rDNA-forming nucleolar-associated domains. The top CpGs were annotated to genes (
