1 · What the graph read from it

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.

2 · The registry

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

Abnormal patterns of DNA methylation are observed in many diseases such as tumors and imprinting disorders. Little is known about inter-individual and gender specific variations. Here, we report on accurate and sensitive quantitative measurements of methylation in DNA from total blood in 96 healthy human males and 96 healthy human females. Global methylation was estimated by studying two repetitive DNA elements, namely Line-1 and Alu repeats, while single loci were investigated for three differentially methylated regions (DMRs) at PEG3, NESP55 and H19 imprinted genes and two additional loci at Xq28 (F8 gene) and at 19q13.4 (locus between PEG3 and ubiquitin specific protease 29). We observed inter-individual correlations in the degree of methylation between Alu and Line-1 repeats. Moreover, all studied CpGs showed slightly higher methylation in males (P < 0.0003-0.0381), with the exception of DMRs at imprinted genes (P = 0.0342-0.9616) which were almost equally methylated in both sexes with only a small tendency towards higher methylation in males. This observed difference could be due to the process of X chromosome inactivation or merely to the presence of an additional X chromosome in female cells or could be a result of downstream effects of sex determination.
