Two proteins from Drosophila nuclei are bound to chromatin and are detected in a series of puffs on polytene chromosomes.
Article in Chromosoma, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Immunizing chromatin protein fractions from Drosophila melanogaster embryos, monoclonal antibodies have been generated against two nuclear proteins of different molecular weight. These proteins are present in a chromatin fraction of Drosophila Kc-cell nuclei and both proteins could be shown to cosediment with nucleosomes following separation on sucrose gradients. Early in development both proteins are located in the embryo cytoplasm. Later, at times when transcription starts at blastoderm, they become redistributed into the nuclei. On salivary gland chromosomes both proteins are detected in a series of developmentally active puffs. The number of sites where these antigens can be detected, as well as the qualitative properties of the antigens at these sites differ between both proteins.
