A new coelacanth (Actinistia, Sarcopterygii) from the Early Triassic of Anhui, China.
Article in Scientific reports, 2025. 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
Coelacanths (e.g., Latimeria) are a curious group of sarcopterygian fishes that survive over hundreds of millions of years and are important in evolutionary biology. In the Early Triassic, coelacanths reached their peak of taxonomic diversity but had only patchy fossil record in Asia. Here, we report the discovery of a new species of the coelacanth genus Whiteia on the basis of two specimens from the late Smithian (~ 249 Ma) marine deposits exposed in eastern Anhui, China. The discovery considerably extends the spatial range of Whiteia in the Early Triassic, and documents the oldest species of the genus in Asia, predating the previously oldest record of whiteiids in this continent by nine million years. The new coelacanth with an estimated total length of at least 420 mm, larger than most of other coelacanths (except Rebellatrix) at its age, represents the largest whiteiid named so far from the Early Triassic and provides an important addition for our understanding the evolution of this major Triassic clade of coelacanths.
