Fig. 1 Cumulative 3-year primary graft patency of ringed and nonringed PTFE femoropopliteal bypass grafts (FP). No significant difference was found between the two groups (p = 0.5).

Fig. 2 Cumulative 3-year primary graft patency of above-knee (AK) ringed and nonringed PTFE femoropopliteal bypass grafts. No significant difference was found between the two groups (p = 0.5).

Fig. 3 Cumulative 3-year primary graft patency of below-knee (BK) ringed and nonringed PTFE femoropopliteal bypass grafts. No significant difference was found between the two groups (p = 0.5).

Fig. 4 Cumulative 3-year primary graft patency of all above-knee (AK) and all below-knee (BK) PTFE femoropopliteal bypass grafts (FEM POPS). The 3-year patency rate of above-knee PTFE femoropopliteal bypass grafts was marginally better than that of below-knee PTFE femoropopliteal bypass grafts (p = 0.25).
