Kaplan-Meier curves showing the 5-year RC rate in NV1, NV2, NV3 and NV4 groups. There was a significant difference between the groups (p=0.002). The statistical analyses between each pair of groups were as follows: NV1 vs. NV2, p=0.750; NV1 vs. NV3, p=0.014; NV1 vs. NV4, p=0.005; NV2 vs. NV3, p=0.004; NV2 vs. NV4, p=0.001; and NV3 vs. NV4, p=0.439.
