a
Patients missing data (12.7%) for concomitant lower extremity revascularization, defined as any bypass or stent to an infrainguinal artery, coded as “No” because unlikely to have had the procedure and not be captured. The 12.7% missing data from distal extent were kept as missing.
b
Attempted percutaneous access counted as percutaneous
