Polytene chromosomes from ovarian pseudonurse cells of the Drosophila melanogaster otu mutant. II. Photographic map of the X chromosome.
Article in Chromosoma, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The banding pattern of the polytene chromosomes of the ovarian pseudonurse cells (PNC) of the Drosophila melanogaster otu mutant were compared with larval salivary gland (SG) polytene chromosomes. The X chromosome was studied and no significant differences were found in the banding pattern between these functionally very different tissues. Most of the differences result from differential puffing activity. In situ hybridisation with five different DNA probes located along the X chromosome was used to cross-check the results obtained by morphological mapping. The constrictions present in the SG chromosomes were found to be absent in the germ line derived PNC chromosomes. There are prominent puffs in the PNC chromosomes at certain locations where genes known to be transcriptionally active in the germ line reside. This suggests that at least some of the genes active in the wild-type nurse cells may also be active in the PNC cells.
