(A) Zinc levels before intervention of patients who had or did not have peripheral arterial disease (“PAD”; n = 4; p = 0.0494). (B) Mean zinc level of our patient cohort before the respective intervention depending on whether we assigned the patients to the group with proven (n = 5) or high suspicion (n = 1) of a genetic predisposition (“inherited”; n = 6; p = 0.9601) or to the group with high atherosclerosis burden ("high-risk"; n = 8; p = 0.0003). (C) Representation of the criteria that we used to categorize patients to the high-risk group (“high-risk”) or not (“normal”). Shown is the mean and SD. Significance was determined using Student's t-test assuming significance if *p < 0.05, **p < 0.01 and ***p < 0.001.
