Schematic illustration of the values AUC1, beta and AUC2. AUC1 is defined as the area under the longitudinal change of values. The beta value is the slope calculated by linear regression over time, and represents the slope of the overall longitudinal change. AUC2 is value obtained by considering the slope and area of the longitudinal change. More specifically, subtraction is performed when the slope is negative, and addition is performed when the slope is positive.
