Delayed Correlations Between Geomagnetic Activity and Human EEG Alpha and Theta Oscillations: Evidence from Archival and Experimental Data.
Article in Brain sciences, 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
Neural oscillations in the alpha and theta bands have been linked to environmental factors, including geomagnetic disturbances, yet the temporal dynamics of these interactions remain poorly understood. This study examined the relationship between geomagnetic activity, quantified by the Kp index, and brain activity in low alpha (7-10 Hz) and theta (4-7 Hz) bands using two complementary approaches. In Experiment 1, archival EEG data from 238 subjects collected over four years were analyzed for correlations between daily Kp values and band power across a ±90-day window. Significant positive correlations (
