Fig. 1From: One-year outcomes of drug-coated balloon treatment for long femoropopliteal lesions: a multicentre cohort and real-world studyKaplan–Meier curves of a Primary Patency and b Target Lesion Revascularization (TLR) Endpoints. Primary patency is defined as freedom from restenosis (> 50% residual lumen diameters in the target lesion under computed tomography angiography, or peak systolic velocity ratio ≤ 2.4 under Doppler ultrasound examination) and freedom from clinically driven TLRBack to article page
