Attention Deficits in Migraine: Mismatch Negativity and P3a in an Event-Related Potential Study.

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
Purpose: Attention performance in chronic migraine remains unclear. The present study aimed to explore the pre-attentive detection and attention orienting ability in individuals with chronic migraine (CM) measured by mismatch negativity (MMN) and P3a components and assess their associations with migraine characteristics. Methods: This cross-sectional observational study recruited 25 individuals with episodic migraine (EM), 25 individuals with CM and 25 healthy controls (HC) matched for age, sex, and educational level. The MMN and P3a components were measured using event-related potential (ERPs) tools with auditory oddball paradigms and migraine characteristics were collected. Results: Individuals with CM exhibited a longer MMN latency (p = 0.010) and a lower P3a amplitude than HC (p = 0.004) and EM (p = 0.002). Correlation analysis showed that P3a amplitude was negatively correlated with headache attack frequency and the Migraine Disability Assessment Scale (MIDAS), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD) scores. Conclusion: Individuals with CM showed deficits in pre-attentive detection and attention orientation. Moreover, attention-oriented dysfunction is associated with headache attack frequency, headache-related disability, anxiety and depression.
