Gravitational symmetry breaking in microtubular dissipative structures.
Article in Proceedings of the National Academy of Sciences of the United States of America, 1992. 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
Reduction-diffusion theories can account for both morphogenesis and the sensitivity of biological systems to weak fields. They predict that gravity can cause the symmetry breaking that is necessary for pattern formation. Microtubules play an important role in organizing the cell, and recent studies hae shown that they can form in vitro dissipative structures. We have found that these structures show patterns of microtubular orientation that are gravity dependent and that the gravitational field causes symmetry breaking. This behavior, which cannot be explained by convection, is in accordance with the theory of dissipative structures. These results suggest that microtubular dissipative structures may play an important role both in morphogenesis and in accounting for the sensitivity of biological systems to weak fields. They aso provide another explanation for biological gravitropism.
