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

In plants, animals, and fungi, DNA methylation is frequently associated with gene silencing, yet little is known about the role of the methylation in silencing. In Neurospora crassa, repeated sequences are silenced by repeat-induced point mutation (RIP) and genes that have suffered numerous GC --> AT mutations by RIP are typically methylated at remaining cytosines. We investigated possible effects on transcription from methylation associated with RIP by taking advantage of 5-azacytidine, which prevents most methylation in Neurospora and a dim-2 mutation that abolishes all detectable methylation. Northern analyses revealed that methylation prevents the accumulation of transcripts from genes mutated by RIP. Measurements of transcription rates in vivo showed that methylation inhibits transcription severely but does not influence mRNA stability. Results of nuclear run-on experiments demonstrated that transcription initiation was not significantly inhibited by the dense methylation in the promoter sequences. In contrast, methylation blocked transcription elongation in vivo.
