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 output effects of the nonspiking interneurones in the crayfish terminal abdominal ganglion upon the uropod motor neurones were characterized using simultaneous intracellular recordings. Inhibitory interactions from nonspiking interneurones to the uropod motor neurones were one-way and chemically mediated. The depolarization of the motor neurones with current injection increased the amplitude of the nonspiking interneurone-mediated hyperpolarization, while hyperpolarization of the motor neurone decreased it. By contrast, excitatory interactions from the nonspiking interneurones to the motor neurones were not mediated via chemical synaptic transmissions. These excitatory connections with the slow motor neurones were one-way while connections with fast motor neurones were bidirectional. Nonspiking interneurone-mediated membrane depolarization of the motor neurones was not affected by the passage of hyperpolarizing current. Each motor neurone spike elicited a time-locked EPSP in the nonspiking interneurones with very short delay (0.2 ms) that suggested electrical coupling between nonspiking interneurones and motor neurones. Nonspiking interneurones directly control the organization of slow motor neurone activity, while they appear to regulate the background activity of the fast motor neurones. A single nonspiking interneurone is possible to inhibit some inter and/or motor neurones via direct chemical synapses and simultaneously excite other neurones via electrical synapses.
