Systematic review	208 people with intermittent claudication or critical limb ischaemia and superficial femoral artery stenosis or occlusion Data from 1 RCT	Improvement in quality of life score 6 months with percutaneous transluminal angioplasty (PTA) plus stent with PTA alone Absolute results not reported Review commented that the type of antiplatelet medication varied between the included RCTs; clopidogrel was given in one large RCT	Mean difference –1.13 95% CI –5.03 to +2.77 Results should be interpreted with caution as it was unclear in some of the RCTs how many people in the PTA alone arm went on to have "bailout" (secondary) stenting and whether or not they were subsequently included in the PTA plus stent arm for analysis, or excluded from the trial		Not significant
