Long-term survival
Total median follow-up for males was 4.7 [1.82-7.8] years and for
females was 4.5 [1.06-7.9] years (p=0.453). Kaplan-Meier survival
estimates were comparable between the two groups (Figure 1, p=0.315,
log-rank). On multivariable Cox proportional hazards regression, sex was
not significantly associated with long-term survival (HR 1.00, 95% CI:
0.73, 1.37, p=0.986, Table 4). Age, African American race, diabetes, and
presence of any malperfusion syndrome were all significantly associated
with an increased hazard of death (HR >1,
p<0.05).
