Impact-induced ultra-high melting point oldhamite discovered in Chang'E-6 lunar soil.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Chang'E-6 lunar soil was the first sample collected on the lunar farside. It provides insights into impact history and thermodynamic evolution of the Moon. Here we show the discovered widespread oldhamite (CaS) in lunar regolith samples. Analysis of the microscopic composition and crystal structure showed that the oldhamite has a cubic structure and presence at the interface of glass and iron on the surface of the impact glass beads, suggesting a interface thermochemical reaction. Thermodynamic calculations show that the formation of chemical reactions requires a reducing atmosphere and high temperature to ensure reducing environment and high iron activity for promoting the interaction. Such environment suggests a potential large-scale, high-energy impact event with a S-rich asteroid or involving lunar S-rich mantle-core excavation. Oldhamite has never been observed in other lunar samples from near side. Our findings reveal a unique evolution history of the South Pole-Aitken basin, which is distinct from nearside.
