After adjusting for age and BMI, FcγR-mediated phagocytosis remained lower in participants with DM2 (mean difference = 13.7; p = 0.07) and was inversely associated with chronic hyperglycemia (β coefficient = −3.0; p = 0.02) or hyperglycemia (β coefficient = −0.11; 0.08). Here, FCGR2A is linked to Hyperglycemia.
