The prevalence of PAD in 6979 men and women, mean age 69 years, screened for PAD by an ABI because they were aged 70 years or older or because they were aged 50 69 years with a history of cigarette smoking or diabetes mellitus was 29% (Hirsch et al 2001).
A total of 745 physicians were excluded because they were aged ≥60 years (n = 158), or because data on working hours during their first pregnancy (n = 528) or pregnancy complications (n = 40) were not available.

Some subjects did not provide a buccal swab sample at inclusion, because they were aged < 18 years (in The Netherlands, these persons are only allowed to provide a DNA sample with parental consent), and DNA sampling was postponed until parental consent was obtained or until they had turned 18 years during follow-up.
