Simulation studies with lognormal distributed and independent random variables. Horizontal axis is the value of the first random variable as the value of lesion volume at baseline, vertical axis is the value of the second random variable as the value of lesion volume at a later Time Point. Dashed first diagonal is the line of equivalence (No change), solid line correspond to thresholds as -35 %; +55 % change. a) Top left: Simulation of random variable having same value (Rejection=3.8 %). b) Top right: Simulation of a 30 % increase of the random variable. (Rejection=20.2 %). c) Bottom left: Simulation of a 55 % increase of the random variable. (Rejection=49.2 %). d) Bottom right: Simulation of 35 % decrease of the random variable. (Rejection=48.8 %)
