Modeling F-actin cortex influence on the secretory properties of neuroendocrine cells.
Article in Communicative & integrative biology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Chromaffin cells are considered as one of the most valuable models to study regulated exocytosis. In these cells, like in other neuroendocrine systems, an intricate cortical cytoskeleton acts as a retentive network impeding vesicle access to plasma membrane. Therefore, during stimulation this structure suffers a transient reorganization allowing active transport of vesicles toward secretory sites. Interestingly, a combination of confocal microscopy studies and mathematical modeling is showing us new aspects of the influence of cortical cytoskeleton in shaping the secretory properties of excitable cells. In this new vision the F-actin-myosin II cortical cytoskeleton is organized forming polygonal cages with the molecular machinery of exocytosis composed by SNARE proteins and voltage-dependent calcium channels associating with its border. In this way the cytoskeleton not only holds together the essential elements acting during secretion, but we proposed that could also act as a structural factor opposing to the free diffusion of the calcium signal and therefore sustains high levels of the intracellular signal triggering exocytosis.
