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

It has been nearly 40 y since it was suggested that genomic methylation patterns could be transmitted via maintenance methylation during S phase and might play a role in the dynamic regulation of gene expression during development [Holliday R, Pugh JE (1975) Science 187(4173):226-232; Riggs AD (1975) Cytogenet Cell Genet 14(1):9-25]. This revolutionary proposal was justified by "... our almost complete ignorance of the mechanism for the unfolding of the genetic program during development" that prevailed at the time. Many correlations between transcriptional activation and demethylation have since been reported, but causation has not been demonstrated and to date there is no reasonable proof of the existence of a complex biochemical system that activates and represses genes via reversible DNA methylation. Such a system would supplement or replace the conserved web of transcription factors that regulate cellular differentiation in organisms that have unmethylated genomes (such as Caenorhaditis elegans and the Dipteran insects) and those that methylate their genomes. DNA methylation does have essential roles in irreversible promoter silencing, as in the monoallelic expression of imprinted genes, in the silencing of transposons, and in X chromosome inactivation in female mammals. Rather than reinforcing or replacing regulatory pathways that are conserved between organisms that have either methylated or unmethylated genomes, DNA methylation endows genomes with the ability to subject specific sequences to irreversible transcriptional silencing even in the presence of all of the factors required for their expression, an ability that is generally unavailable to organisms that have unmethylated genomes.
