Zero-Field Overhauser Dynamic Nuclear Polarization.
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
Overhauser dynamic nuclear polarization (O-DNP) enables the production of hyperpolarization in liquids via the dissolution of nitroxide radicals. However, the application of magnetic fields has been inevitable. In the present study, we experimentally demonstrate that water can be hyperpolarized through O-DNP at effectively zero magnetic field. Selective saturation induced by circularly polarized RF fields, generated by two orthogonal RF coils, effectively circumvents the concurrence of positive and negative polarizations that would otherwise significantly deteriorate O-DNP efficiency. Through electron-to-nuclear spectral mapping, the electron paramagnetic resonance spectrum of the nitroxide radical was recorded at a magnetic field of 2 nT. A direct comparison revealed that O-DNP with circularly polarized RF is more than 10
