Evaluating Palladium 4d-to-2p X-ray Emission Spectroscopy for Characterizing Catalytically Relevant Species.
Article in Inorganic chemistry, 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
X-ray absorption spectroscopy (XAS) has diverse applications in materials characterization and catalysis. While K-edge XAS can provide detailed information about electronic and geometric structures for 3d transition metals, its application to second- and third-row transition metals is often limited by substantial core-hole lifetime broadenings. For the later transition metals, higher d-electron counts further reduce the electronic structural information content due to weak and absent 1s-to-nd pre-edge features. L-shell X-ray emission spectroscopy (XES), specifically 4d-to-2p XES, can overcome these limitations by accessing transitions that are dipole allowed and have intrinsically narrower core-hole lifetime broadenings. Herein, the utility of Pd 4d-to-2p XES for in situ catalysis research in both homogeneous and heterogeneous systems is explored through the study of well-defined PdO
