Text: Of 216 participants analyzed, including 97 with arteriovenous grafts (AVG) (49 FIR-radiated participants and 48 control participants) and 119 with arteriovenous fistulas (AVF) (69 FIR-radiated participants and 50 control participants), the FIR-radiated therapy compared with free-radiated usual therapy significantly enhanced PTA-unassisted patency at 1 year in the AVG subgroup (16. 3 % vs. 2. 1 % ; p <. 01), but not the AVF subgroup (25. 0 % vs. 18. 4 % ; p =. 50), and this accounted for the overall improved patency rates (21. 4 % vs. 10. 3 % ; p =. 02).
