In addition, serum CCR2 levels were significantly increased in ischemic stroke patients compared to healthy controls (Figure 2b, U = 218, p = 0.0009) and CCR2 levels correlated significantly with time to blood sample (Spearman’s rho = −0.28, p = 0.04), SSS (Spearman’s rho = −0.26, p = 0.04), and mRS (Spearman’s rho = 0.31, p = 0.045). Here, CCR2 is linked to ischemic stroke.
