Multiple variable survival analysis of factors associated with access survival
| Type of access survival | Clinical variable | HR (95% CI) | P |
|---|---|---|---|
| Cumulative survival including primary failures | Males vs female | 0.80 (0.65 to 0.97) | 0.02 |
| Prior access | 1.26 (1.04 to 1.54) | 0.02 | |
| Cumulative survival excluding primary failures | BC fistula vs graft | 0.53 (0.40 to 0.70) | <0.001 |
| BB fistula vs BC fistula | 1.07 (0.67 to 1.70) | 0.78 |
BB, brachiobasilic; BC, brachiocephalic.
Cox proportional survival analysis was modeled with the following clinical variables: access type, patient age, sex, diabetes, coronary artery disease, peripheral vascular disease, cerebrovascular disease, and prior access.
