Diverse mechanical properties, composition, and performance of shark dermal denticles.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Sharks have roamed the oceans since the Devonian, surviving multiple mass extinctions. Today, sharks are agile, streamlined swimmers, ambush predators hiding beneath the sand, and giants cruising in slow motion. Impressively, they are all covered in an armour of tiny skin teeth (dermal denticles). We quantify dermal denticle disparity using deep learning on scanning electron microscopy images, discerning ten morphogroups across modern sharks (Selachii). Seven of the ten morphogroups display ridged denticles. Through nanoindentation, electron probe micro-analysis, and computational fluid dynamics, we establish mechanical properties, elemental composition, and swimming performance, and find that denticle ridges are highly variable and present a spectrum of functional properties beyond drag reduction. Further, we identify a potential correlation between a radiation event within the ground sharks Carcharhiniformes around 170 MYA, resulting in the enormous diversity of the clade, and ridged dermal denticles.
