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

Previous studies have established that the Snf2h-containing chromatin remodeling complex NoRC mediates epigenetic silencing of a subset of rRNA genes (rDNA) by recruiting enzymatic activities that modify histones and methylate DNA. Here we have analyzed nucleosome positions at the murine rDNA promoter and show that active and silent rDNA copies are characterized not only by specific epigenetic marks but also by differently positioned nucleosomes. At active genes the promoter-bound nucleosome covers nucleotides from -157 to -2, whereas at silent genes the nucleosome is positioned 25 nucleotides further downstream. We provide evidence that NoRC is the molecular machine that shifts the promoter-bound nucleosome downstream of the transcription start site into a translational position that is unfavorable for transcription complex formation.
