Continuous data are presented as the means ± standard deviation; categorical data are given as the counts (percentage).
Multivessel disease is defined as both femoropopliteal disease and below the knee disease.
Heavy calcification is defined as the presence of at least 5 mm of calcification on both sides of the vessel.
