Does primary stenting have a lower 12-month restenosis rate than PTA alone in the treatment of atherosclerotic lesions of the popliteal artery?
- Alternative hypothesis: "Primary stenting with the Edwards LifeStent is associated with a lower restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery at 12 months"
- Null hypothesis: "Primary stenting with the Edwards LifeStent is not associated with a lower 12-month restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery""
- Does comparison of the two intervention groups (PTA alone, stenting) disclose differences in terms of the secondary endpoints?
- How do the intervention methods compare in terms of safety/incidence of adverse effects?
- What are the long-term clinical implications of the two treatment methods?
