Headache-specific hyperexcitation sensitises and habituates on different time scales: An event related potential study of pattern-glare.
Article in Neuroimage. Reports, 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
Cortical hyperexcitability is a key pathophysiological feature in several neurological disorders, including migraine, epilepsy, tinnitus, and Alzheimer's disease. We examined the temporal characteristics of Event Related Potentials (ERPs) in a healthy population using the Pattern Glare Test, a diagnostic tool used to assess patients with sensitivity to cortical hyperexcitability. In pre-experiment questionnaires, participants reported their susceptibility to a range of symptoms. A factor analysis over these responses identified three variables, with the one we investigate in this paper loading strongly on headache symptoms, e.g. headache frequency. We investigated two timeframes: habituation over the course of the entire experiment and sensitization over the course of a sequence of stimulus presentations. We found evidence of hyperexcitability at electrodes over visual cortex, for the aggravating stimulus (grating of ∼3 cycles/deg). Participants higher on the headache factor exhibited a higher degree of habituation and sensitization, with evidence that the level of sensitization habituated through the course of the experiment. These findings suggest that the same experimental paradigm and analysis should be performed on a clinically diagnosed population.
