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

The suppressor of Hairy-wing [su(Hw)] protein mediates the mutagenic effects of the gypsy retrotransposon by blocking enhancer activity. These repressive effects are general, can occur over long distances and require that the su(Hw) protein is bound between the affected enhancer and promoter. The effects of the su(Hw) binding region on yolk protein (yp) gene expression were determined. These genes are regulated by shared enhancers in the intergenic region, which provided a method to examine whether an enhancer blocked by the su(Hw) protein remained functional. We demonstrate that a blocked enhancer is completely active, supporting the proposal that the su(Hw) protein is an insulator protein that acts by forming a new boundary in a pre-existing chromatin domain, thereby preventing the interaction of regulatory elements located upstream of the insertion site with the promoter. In addition, we found that yp promoter function is not diminished by sharing enhancers, suggesting that these enhancers are not rate limiting for transcriptional activation. Lastly, our data indicate that yp promoter activity is interdependent, such that transcription from one promoter influences the level of activity of the linked promoter.
