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).
