The role of clinical evidence in emergent therapies: an empirical study on femoropopliteal stent-angioplasty in Europe.

A delayed availability of clinical evidence in rapidly emerging therapies is considered a major problem. In this study, we examined whether evidence from clinical studies has influenced the therapy of a major disease in industrial countries, peripheral arterial disease (PAD), using novel femoropopliteal stent-angioplasty.
