Design outcomes

Primary

MeasureTime frame
Change in hemoglobin level between baseline and 24 weeks after randomization

Secondary

MeasureTime frame
Changes in laboratory tests , ABI, duplex ultrasound (PSV, PSVR), QOL score (EQ-5D-5L, SF-36v2, PHQ-9, Vascu-QOL, WIQ), 6 minutes walking distance between baseline and 24 weeks. Clinical outcomes at 24 weeks (all-cause death, cardiovascular death, non-cardiovascular death, myocardial infarction, unplanned coronary revascularization, unplanned peripheral revascularization, stroke, admission due to heart failure, bleeding, lower limb amputation, hemodialysis)
