Specimen-level phylogenetic analysis and taxonomic revision of North American metoposaurids: a case for monospecific genera in vertebrate paleontology.
Article in PeerJ, 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
The Metoposauridae were a widespread family of aquatic Late Triassic temnospondyl amphibians known from numerous localities in non-marine strata of the Northern Hemisphere, India, and Madagascar. Recent descriptions of intraspecific variation in skulls from hyper accumulations suggest some characters used in species diagnoses may be variable within hypothesized populations. This realization necessitates the reevaluation of taxonomic diagnoses for previously established species. Multiple monospecific hyper accumulations of different metoposaurid taxa are known in North America providing a relatively large sample to assess the validity of the North American taxa:
