Further analysis showed elevated CCL2 serum levels in the group with early AMD compared to controls (median (IQR): 1181.6 (522.6) pg/mL vs. 879.9 (494.4) pg/mL, p = 0.013); however, there were no differences between CCR2 serum levels within groups. Here, CCR2 is linked to age-related macular degeneration.
