Using PRINS for gene mapping in polytene chromosomes.

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
We have adapted the primed in situ labelling (PRINS) protocol for gene mapping in polytene chromosomes of two dipteran species. The method was used to localize the genes for the Balbiani ring (BR) 2.1 and the iron-regulatory protein 1A (IRP1A) in polytene salivary gland chromosomes of Chironomus tentans, and Drosophila melanogaster respectively. Two oligonucleotides, corresponding to the BR 2.1 and IRP1A genes, were used as primers and the whole procedure was performed within 3-4 h. The strong labelling with low background revealed the localization of the BR 2.1 gene in polytene chromosome IV of C. tentans and the IRP1A gene in polytene chromosome 3R83 of D. melanogaster. The results demonstrated that PRINS is a fast, sensitive and suitable approach for physical gene mapping in polytene chromosomes.
