Plot of predicted probabilities (Y-axis) vs. the EP score (X-axis). The dotted line represents patients with TT2 > 3 yrs; the solid line represents patients with TT2 ≤ 3 yrs. The difference between the curves is largest at the origin of the EP axis and tends to decrease as the EP values grow until it eventually becomes negligible at approximately an EP score of 20.
