The serum levels of ficolin-2, ficolin-3 and CRP were measured in the samples obtained from 65 stroke patients on admission and 3-4 days later (follow-up samples), as well as in the sera of 100 healthy volunteers and 134 patient controls (patients with severe carotid atherosclerosis without acute stroke) (Figure 1). Here, CRP is linked to carotid atherosclerosis.
