Figure 4: Treg percentages in patients and controls and the relationship between the percentage of circulating Tregs and the FA value of the anterior limb of the internal capsule in patients. (A) The percentage of circulating Tregs differed significantly in the stoke patient and healthy control groups (F1,36 = 7.89, p = 0.008). (B) In stroke patients, a significant correlation was observed between the percentage of circulating Tregs and the FA value (r=0.50, p=0.04).
