Physics of actin networks. I. Rheology of semi-dilute F-actin.
Article in Biophysical journal, 1995. 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 mechanical properties of cytoplasm are considered to be of underlying importance in the mechanism of cell movement and are to a large extent determined by an actin-containing cytoskeleton. Several laboratories have begun to accumulate data on the mechanical or rheologic properties of protein systems derived from the actin cytoskeleton. The focus of this manuscript is to attempt to reproduce the experimentally determined mechanical properties of non-cross-linked F-actin from theoretical considerations. It was found that a mechanical spectrum for 1 mg/ml F-actin could be calculated, which approximated experimental data, from a relaxation spectrum consisting of a long range rotational diffusion motion and short range bending motion, assuming an exponential distribution of filament lengths with a weight average length of 4 mu. The calculated spectrum underestimated the dynamic moduli at high frequencies, suggesting that a more complex actin structure is present that enhances the high frequency component.
