Fig. 4: Associations between relative amplitude and regional MRI measures.

Analyses were adjusted by age, sex, Townsend deprivation index, ethnicity, and wear season. Initial continuous relative amplitude was inverted by multiplying −1. R-value represents the correlation coefficient of the linear regression. Here, we only show the regions with FDR-corrected p-value < 0.05. a, b Cortical thickness and subcortical volume. c White matter tract-specific FA (from left to right: superior, anterior, posterior, and left lateral views).
