Inter- and Intraspecific Variation in Dorsal Pigmentation Patterns of Skates (Rajidae) from the Cantabrian Sea: Evidence of High Variability in
Article in Biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Accurate species identification is essential to assess population trends and implement effective conservation measures. Many rajid species have life-history characteristics that increase their vulnerability to fishing mortality, while their conservation status differs among species. However, species identification within the family Rajidae is hampered by morphological conservatism and intraspecific phenotypic variation, which frequently lead to misidentification in fisheries surveys and seafood markets. Here, we combine COI DNA barcoding with a detailed photographic assessment of dorsal pigmentation patterns in 484 skate specimens collected from a fish wholesaler market in the Cantabrian Sea. Seven species were genetically identified as
