Fig 1 Kaplan-Meier curves presenting patency in percent (y-axis) over the time after bypass reconstruction in months (x-axis). Number at risk (No. at risk), patency (%) and standard error (%) for years 1 to 5 are presented in tabular form. A, Kaplan-Meier estimates for primary patency according to disease stage: Fontaine stage IIb vs III vs IV: 1 year: 67% vs 62% vs 36%, P < .05; 3 years: 58% vs 48% vs 26%, P < .05. B, Kaplan-Meier estimates for primary patency according to preoperative antiplatelet medication: yes vs no: 1 year: 67% vs 52%, P < .05; 3 years: 56% vs 42%, P > .05. C, Kaplan-Meier estimates for primary patency according to graft diameter: 8-mm vs 6-mm prostheses: 1 year: 72% vs 49%, P > .05; 3 years: 58% vs 42%, P < .05.
