Comparison of mean cortical thickness of brain areas showing correlation with Eyes test performance between patients with multiple sclerosis and healthy control group.

a comparisons between patients with MS and HC were controlled for age.1 multiple sclerosis.2 healthy controls.According to the performance in the Eyes test, patients with multiple sclerosis (n = 49) were divided into impaired (n = 19) and non-impaired (n = 30) subgroups. Impaired social cognitive performance was defined as test performance 1 standard deviation below the mean of the performance of the healthy control group (n = 18) recruited for the cortical thickness measure.
