Mean cortical thickness computed by the two analysis strategies over 6Â years of follow-up in MS patients. Using the data without lesion filling, an increase of the mean CTh after 3Â years and a drop after 6Â years is observed. Correcting the misclassification of WM lesions, instead, produces an evolution of the mean CTh as expected in MS patients. BL: baseline; Y3: follow-up after 3Â years; Y6: follow-up after 6Â years.
