Analysis of the role of microtubules and actin in erythrophore intracellular motility.
Article in The Journal of cell biology, 1983. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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 Holocentrus erythrophore, a red pigment cell, represents a model system for the study of organized intracellular transport. We have investigated the possibility that microtubules and actin are integral components of the pigment translocating motility machine. By creating cells that have total or partial loss of the microtubule framework we have demonstrated that the presence of microtubules is essential for organized, radial transport of the pigment granules. However, in the absence of microtubules, some undirected movement of the pigment can be stimulated; this suggests that a nonmicrotubular component of the cytoplast is responsible, at least in part, for the generation of motive force. In order to test the hypothesis that this component consists of actin or actomyosin, we examined the effects of probes for these classical motility proteins. Neither microinjection of phalloidin, DNase I or N-ethylmaleimide-modified heavy meromyosin nor exogenous application of cytochalasin B has any effect on pigment motion, although these materials do block the actin-mediated motility of other systems in our hands. Therefore, intracellular particle transport in erythrophores does not appear to be actin or actomyosin-based.
