Values are number (percent) of patients or mean ± SD.  The percentages were calculated based on number of patients with available information.
aHigh blood pressure was defined as systolic ≥140 or diastolic ≥90 mm Hg.
bAbsent posterior tibial or dorsalispedis arterial pulse on either side.
cDyslipidemia was defined as triglycerides >150 mg/dl (1.7 mmol/l), low density lipoprotein (LDL) >100 mg/dl (2.6 mmol/L) or HDL <40 mg/dl (1.0 mmol/l) in men and <50 mg/dl (1.3 mmol/l) in women.
dAbnormal fat composition was as >23% in males and >27% in females.
eLowest determination in each patient; p-value between the genders = 0.071 (Mann-Whitney U test).  The categories are based on Al-Qaisi et al., 2009.
