Geochemical Characteristics of Late Permian Coal in Western Guizhou, China, and Their Paleoenvironmental Significance.
Article in ACS omega, 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
The Late Permian coal deposited in eastern Yunnan and western Guizhou provided a record of changes in the paleoclimate and paleoenvironment before the main episode of the end-Permian mass extinction. Studying the geochemical characteristics of elements of coal provides important insights into the evolution of the paleoenvironment. Focusing on the Late Permian coal of the Longtan Formation from Dawan Mine, Liupanshui Coalfield in western Guizhou, the geochemical characteristics were determined by using X-ray fluorescence spectrometry and inductively coupled plasma-mass spectrometry. The contents of the major elements were depleted to normal compared with that of Chinese coal. Compared to world coal, there was a slight enrichment in Cu, Co, Zr, Hf, V, and Nb, while Ba, Sr, and Cs were depleted, and the other trace elements and rare earth elements were present at normal levels. The salinity- and redox-sensitive proxies (e.g., Sr/Ba, V/(V + Ni), Ce
