Adaptive loss of shortwave-sensitive opsins during cartilaginous fish evolution.
Article in Nature communications, 2025. 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
Cartilaginous fishes (e.g., sharks, rays, and skates) cannot see blue or violet light, potentially because they lack the shortwave-sensitive cone opsin gene (sws). Widespread gene loss can occur during evolution, but the evolutionary mechanisms underlying sws loss remains unclear. Here, we construct whole-genome assemblies of Okamejei kenojei (skate) and Prionace glauca (blue shark). We then analyze the distribution characteristics and intragroup differences of opsin-related genes in cartilaginous fishes. Using a zebrafish model with sws deleted we infer that in the presence of SWS1 and SWS2, blue and violet light respectively, can induce cell aging. This is followed by photoreceptor layer thinning, demonstrating, sws loss aids in preventing shortwave light damage to the eye. In the retinas of numerous cartilaginous fishes, the tapetum lucidum strongly reflects light. Therefore, in cartilaginous fish, the existence of tapetum lucidum in the retina and loss of sws may be interdependent; in other words, this adaptive gene loss may increase cartilaginous fish fitness.
