Fig. 3 One-year results of 73 infrainguinal autologous revascularization procedures in 68 patients. Analysis is by the life table method. Standard error bars have been removed for clarity, but all were <10%. Number of grafts at risk per interval (primary patency rate) is shown at bottom.

Fig. 4 One-year primary patency data of 73 infrainguinal bypass grafts according to low and high ∫ZL. Analysis is by the life table method. Difference between the curves is highly statistically significant (p < ). Number of grafts at risk per interval is shown at bottom.

Fig. 5 One-year primary patency data of 73 infrainguinal bypass grafts according to low and high stimulated R.44 Analysis is by the life table method. Difference between the curves is not statistically significant. Number of grafts at risk per interval is shown at bottom.
