Modification of position-effect variegation by competition for binding to Drosophila satellites.
Article in EMBO reports, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
White-mottled (w(m4)) position-effect variegation (PEV) arises by translocation of the white gene near the pericentric AT-rich 1.688 g/cm3 satellite III (SATIII) repeats of the X chromosome of Drosophila. The natural and artificial A*T-hook proteins D1 and MATH20 modify w(m4) PEV in opposite ways. D1 binds SATIII repeats and enhances PEV, presumably via a recruitment of protein partners, whereas MATH20 suppresses it. We show that D1 and MATH20 compete for binding to identical sites of SATIII repeats in vitro and that conditional MATH20 expression results in a displacement of D1 from pericentric heterochromatin in vivo. In the presence of intermediate levels of MATH20, we show that this displacement becomes selective for SATIII repeats. These results strongly suggest that the suppression of w(m4) PEV by MATH20 is due to a displacement of D1 from its preferred binding sites and provide additional support for a direct role of D1 in the assembly of AT-rich heterochromatin.
