Figure 3: Representation of the survival curve separated by age groups (<20, n=7; 20–<40, n=112; 40–<60, n=103; ≥60, n=39) using the Kaplan-Meier survival function. The intersection of the curves with the solid horizontal line stands for the 5-year success rate, the intersection with the dashed horizontal line for the 10-year success rate.
