Data on carotid atherosclerosis and advanced atherosclerosis, which are defined in our study as the presence of at least a single (CP) and multiple carotid plaques (MCP), respectively, were available for only 34% of the participants, with 50/23/14 and 55/23/2 total/CP/MCP samples available for males and females. Here, CP is linked to carotid atherosclerosis.
