Reactive formation of magnesiowüstite at the lunar core-mantle boundary.
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
Seismological and geodetic data indicate that the lunar core-mantle boundary (CMB) exhibits a well-defined low-velocity zone (LVZ) with a combination of anomalous seismic velocities and density that remain unexplained. Here, in-house high-pressure experiments simulating the interaction between mantle olivine and core iron at CMB conditions in conjunction with thermodynamic modeling demonstrate reactive formation of dense iron-rich magnesiowüstite [Mw, (Fe,Mg)O], a hitherto unrecognized lunar mineral. In-situ synchrotron ultrasonic measurements show that the seismic velocities and density of Mw, when incorporated in realistic proportions of ~5-15 wt% with mantle olivine plus minor silicate melt match the observed LVZ properties. Oxygen exsolution from core metal during cooling is the most likely driver of Mw formation, quantitatively yielding the required Mw proportions in the LVZ. These results suggest that core-mantle reactions can generate magnesiowüstite through oxidation of iron metal, offering a blueprint for the expected seismic properties of the CMB regions of rocky bodies that experience mantle oxidation after core formation.
