Genome-wide signatures of mammalian skin covering evolution.
Article in Science China. Life sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Animal body coverings provide protection and allow for adaptation to environmental pressures such as heat, ultraviolet radiation, water loss, and mechanical forces. Here, using a comparative genomics analysis of 39 mammal species spanning three skin covering types (hairless, scaly and spiny), we found some genes (e.g., UVRAG, POLH, and XPC) involved in skin inflammation, skin innate immunity, and ultraviolet radiation damage repair were under selection in hairless ocean mammals (e.g., whales and manatees). These signatures might be associated with a high risk of skin diseases from pathogens and ultraviolet radiation. Moreover, the genomes from three spiny mammal species shared convergent genomic regions (EPHB2, EPHA4, and NIN) and unique positively selected genes (FZD6, INVS, and CDC42) involved in skin cell polarity, which might be related to the development of spines. In scaly mammals, the shared convergent genomic regions (e.g., FREM2) were associated with the integrity of the skin epithelium and epidermal adhesion. This study identifies potential convergent genomic features among distantly related mammals with the same skin covering type.
