  • Values are n (%). BMS indicates bare metal stent; CLI, critical limb ischemia; DES, drug‐eluting stent; PTA, percutaneous transluminal angioplasty.

  • a Number of limbs/lesions with available diagnostic imaging and those with treatment failure. Imaging unavailable for 9 limbs in the PTA‐BMS group and 8 limbs in the DES group. Limbs/lesions in patients deceased due to unrelated causes were censored (10 limbs in PTA‐BMS, 10 limbs in DES).

  • b P value weighted by number of lesions per patient.
