Dual effect of filamin on actomyosin ATPase activity.
Article in Journal of muscle research and cell motility, 1985. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Filamin binds to F-actin and influences the myosin-actin interaction. At relatively low concentrations, filamin activates actomyosin Mg2+-ATPase, whereas higher concentrations of filamin exert an inhibitory effect. Activation of ATPase activity occurs under conditions where a loose meshwork of actin filaments is present and inhibition is associated with the appearance of closely apposed bundles of actin filaments. Maximum activation (about fourfold) of actomyosin ATPase activity by filamin occurs between 30 and 65 mM KCl, at pH 6.5, and at temperatures not less than 30 degrees C. ATPase activation requires higher concentrations of filamin in the presence than in the absence of tropomyosin. Filamin does not activate Mg2+-ATPase activity of acto-subfragment-1 and has only a slight effect on the Mg2+-ATPase of acto-heavy meromyosin, but it inhibits the activity of both these systems under conditions similar to those that inhibit actomyosin ATPase activity.
