Magnetoreception: activation of avian cryptochrome 1a in various light conditions.
Article in Journal of comparative physiology. A, Neuroethology, sensory, neural, and behavioral physiology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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 avian magnetic inclination compass is based on radical pair processes, with cryptochrome (Cry) assumed to form the crucial radical pairs; it requires short-wavelength light from UV to green. Under high-intensity narrow-band lights and when yellow light is added, the magnetic compass is disrupted: migratory birds no longer prefer their migratory direction, but show other orientation responses. The candidate receptor molecule Cry1a is located in the shortwavelength-sensitive SWS1 cone photoreceptors in the retina. The present analysis of avian retinae after the respective illuminations showed that no activated Cry1a was present under 565 nm green light of medium and high intensity, and hardly any under high intensity 502 nm turquoise, whereas we found activated Cry1a at all three tested intensities of 373 nm UV and 424 nm blue light. Activated Cry1a also was found when 590 nm yellow light was added to low-intensity light of the four colors; yet these light combinations result in impaired magnetic orientation. This indicates that the disruption of the magnetic compass does not occur at the receptor level in the retina, but at higher processing stages, where the unnatural, almost monochromatic or bichromatic illumination causes yet unknown responses that interfere with the inclination compass.
