Atherosclerotic Plaque Characteristics in the Superficial Femoral Artery Associated with Presence or Absence of Lipid Rich Necrotic Core in Adults with Peripheral Arterial Disease (n=303)

Analyses Adjusted for Age and Sex
Normalized plaque
measures, (SE)		 LRNC absent
(n=235)		 LRNC present
(n=68)		 P value
Mean percent lumen area 33% (1%) 31% (2%) 0.42
Minimum percent
lumen area		 24% (1%) 22% (2%) 0.24
Mean wall area 0.70(0.01) 0.71 (0.02) 0.67
Maximum wall area 0.92 (0.03) 0.96 (0.05) 0.54

SE indicates standard errors; LRNC, lipid rich necrotic core. Mean and maximum wall areas are normalized for vessel size.
