Light-induced structural changes of cytoskeleton in squid photoreceptor microvilli detected by rapid-freeze method.
Article in The Journal of cell biology, 1988. 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
The cytoskeleton in squid photoreceptor microvilli was studied by freeze-substitution electron microscopy combined with rapid freezing using liquid helium, under dark-adapted and light-illuminated conditions. In the dark-adapted microvilli, actin filaments were regularly associated with granular structures on their surface; these granular structures were cross-linked to the rhodopsin-bearing plasma membranes through slender strands. Upon exposure to light, the granular components detached from the actin filaments, which then appeared to be fragmented and/or depolymerized. These observations have led us to conclude that light stimulation triggers the breakdown of the microvillar actin filament complex in squid photoreceptor cells. The results are discussed with special reference to the physiological role of actin filaments in photoreception.
