A functional in vitro model for studies of intracellular motility in digitonin-permeabilized erythrophores.
Article in The Journal of cell biology, 1982. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Phase contrast cine results demonstrate that erythrophores maintain saltatory particle motion for hours after permeabilization with 0.001% digitonin in a cytoskeletal stabilizing solution at 23 degrees C. High voltage electron microscopy (HVEM) studies reveal that cytoskeletal elements are retained intact, except in immediate subplasmalemmal regions where the plasma membrane is punctured by digitonin. During digitonin treatments, cells are permeable to ions, small molecules, and antibodies. We find that motion is Ca2+ and ATP-sensitive, and optimal in PIPES buffer (pH 7.2 containing 1 mM Mg2+/ATP and EGTA-CA2+ (10(-7) M Ca2+) at 37 degrees C. Experiments testing the inhibitory effects of vanadate (0.4-10 microM), ouabain (100-600 microM), N-ethyl maleimide, and the cytochalasins B and D indicate that a dyneinlike ATPase may provide the motive force for driving saltatory pigment motion in erythropores.
