Mid-term Survival
Ninety-one patients were included in the follow-up, and the other 21
patients were lost during follow-up because of changing contacts. Six
patients died due to MACE during follow-up. The overall median follow-up
time was 65 months (IQR 28-101 months). The mean survival time estimate
was 147.2 (95% Cl 135.6-158.9) months, with a 3-year survival rate of
91.2% and a 5-year survival rate of 89.0%.
After grouping, the median survival time estimates for the low ΔDR group
and the high ΔDR group were 154.9 (95% Cl 143.9-166.6) months and 113.8
(95% Cl 88.9-138.6) months respectively. Kaplan-Meier overall survival
curves and number at risk table for patients with low ΔDR group and high
ΔDR showed a statistically significant difference (Log-rank chi-square
5.775; p = 0.016).(Figure 2)
