Fig 2 Stent grafts improve primary patency of target lesion and access circuit compared with balloon angioplasty. Kaplan-Meier estimates of primary patency of the target lesion (A) and access circuit (B). In all cases, stent grafts demonstrated statistical superiority in patency compared with balloon angioplasty. (P values shown in each panel were calculated using the log-rank test). EPP, Effectiveness-per-protocol; ITT, intention to treat; PTA, percutaneous transluminal angioplasty.
