Figure 5 Major Amputation Events According to TAC Score for Patients With PAD
Symptomatic vascular patients were stratified by tibial artery calcification (TAC) scores >400 or <400. Kaplan-Meier curves were derived for major amputation-free survival. The p value is derived using the log-rank test. Number of patients at risk at each time point is listed on the bottom. PAD = peripheral arterial disease.
