3.4.1 DSA
Of the 224 patients in this study, 18 (8%) experienced DSA and the
median time for DSA incidence was 1088 days (IQR, 592–1677 days).
Kaplan-Meier analysis revealed that
DSA incidence was 12.5% and 5.6% in the Low and High
C0 group, respectively (P = 0.025) (Figure 4A).
Additionally, the High IPV group also demonstrated a higher frequency of
DSA compared to the Low IPV group, although this difference did not
reach statistical significance (11.1% versus 4.7%, P = 0.056)
(Figure 4D). From the Cox
proportional hazard model, Low C0 was independently
associated with increased risk for DSA (HR 2.820, 95% CI 1.093–7.276,P = 0.032) (Table 2).
