The open bars represent the percentage of survivors (left Y-axis) whereas the filled bars stand for the complementary percentage of mortality (right Y-axis). As can be observed, at 3, 6, and 9 years follow-up, only 7%, 21%, and 43%, respectively, of patients in the low-risk group had died. Such proportions progressively increased in the intermediate-1 and intermediate-2 groups, being 69%, 96%, and 100% in the high-risk group.

Median time (months) and the 95% CI were calculated at percentiles 75th, 50th, and 25th of the survival time by re-sampling the original series. As can be seen, no significant overlapping was noted in the survival curves.
