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

Transcriptional repression occurs during meiotic maturation of Xenopus oocytes. Injection of a DNA template containing an hsp70 promoter into Xenopus oocytes, followed by progesterone-induced maturation has been used to demonstrate a dynamic competition between the assembly of transcription factor-containing nucleoprotein complexes and repressive nucleosomal arrays during the maturation process. In particular, it is shown that increased levels of injected heat shock protein, the transcriptional activator Gal4-VP16 or the DNA template itself all lead to reduced repression of transcription on maturation. Conversely, injection of additional histone increases repression. Repression of transcription is shown to be accompanied by the formation of a more regular array of nucleosomes and by an increase in the efficiency of nucleosome assembly on the injected plasmid. Meiotic maturation is therefore accompanied by replacement of transcription factor complexes by a repressive chromatin environment.
