A non-flight muscle isoform of Drosophila tropomyosin rescues an indirect flight muscle tropomyosin mutant.
Article in Journal of muscle research and cell motility, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 tropomyosin I(TmI) gene of Drosophila melanogaster encodes two isoforms of tropomyosin. The Ifm-TmI isoform is expressed only in indirect flight and jump muscles; the Scm-TmI isoform is found in other muscles of the larva and adult. The level of Ifm-TmI is severely reduced in the flightless mutant Ifm(3)3, which also is unable to jump. To explore the functional significance of tropomyosin isoform diversity in Drosophila, we have used P element-mediated transformation to express Scm-TmI in the indirect flight and jump muscles of Ifm(3)3 flies. Transformants gained the ability to jump and fly. The mechanical properties of isolated indirect flight muscle myofibres, and the ultrastructure of indirect flight and jump muscles from the transformants were comparable to wildtype. Thus, the Scm-TmI isoform can successfully substitute for Ifm-TmI in the indirect flight and jump muscles of the Ifm(3)3 strain.
