The Vantaa dataset had 27 early-stage cases with minimal Lewy-type pathology ordered into amygdala-predominant, brainstem/PNS-predominant cases, and other cases categories. Each row in the table represents a distinct pattern of pathology shared by a number of cases (# cases). An “x” signifies the presence of Lewy-type pathology in individual anatomical structures. The three right-most columns list the total number of cases of each type, the number of OB-positive cases, and the percentage of OB-positive cases.
