The disturbance of the fast axonal transport of protein by passive stretching of an axon in Aplysia.
Article in The Journal of physiology, 1987. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
1. Radioactive amino acid, either [3H]leucine or [3H]proline, was injected into neurone R2 in the abdominal ganglion of Aplysia kurodai to investigate the intra-axonal transport of protein in a single axon. 2. Some of the injected amino acid which was not utilized for protein synthesis diffused intra-axonally with a diffusion constant of 6.0 X 10(-6) cm2/s (25 degrees C), which is the value expected from the known diffusion constants of acetylcholine and gamma-aminobutyric acid in the axoplasm (Koike & Nagata, 1979). The true length of the zigzagging axon in the nerve bundle was measured by the diffusion distances. 3. The radioactive proteins newly synthesized in the cell body from either of the injected amino acid were transported axonally in a single axon of R2. 4. Elongation of the axon resulted in a suppression of the fast axonal transport of the proteins and the amount of protein transported. This contrasts with the observation that action potential propagation along the elongated axon never failed. 5. A possible site for the suppression of the axonal transport would be axonal microtubules whose structure is not likely to be resistant to the distortion caused by the elongation.
