The table illustrates the statistical analysis performed separately on cortical thickness and gyrification between: healthy patients and patients; subgroups of healthy controls and subgroups of patients. Cohort 1 and cohort 2 indicate the two groups of patients compared for each statistical analysis and n° indicates the number of patients forming a particular cohort.
MMD: migraine monthly days.
