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

Boundary elements have been found in the regulatory region of the Drosophila melanogaster Abdominal-B (Abd-B) gene, which is subdivided into a series of iab domains. The best-studied Fab-7 and Fab-8 boundaries flank the iab-7 enhancer and isolate it from the four promoters regulating Abd-B expression. Recently binding sites for the Drosophila homolog of the vertebrate insulator protein CTCF (dCTCF) were identified in the Fab-8 boundary and upstream of Abd-B promoter A, with no binding of CTCF to the Fab-7 boundary being detected either in vivo or in vitro. Taking into account the inability of the yeast GAL4 activator to stimulate the white promoter when its binding sites are separated by a 5-kb yellow gene, we have tested the functional interactions between the Fab-7 and Fab-8 boundaries and between these boundaries and the upstream promoter A region containing a dCTCF binding site. It has been found that dCTCF binding sites are essential for pairing between two Fab-8 insulators. However, a strong functional interaction between the Fab-7 and Fab-8 boundaries suggests that additional, as yet unidentified proteins are involved in long-distance interactions between them. We have also shown that Fab-7 and Fab-8 boundaries effectively interact with the upstream region of the Abd-B promoter.
