We screened UA-related covariables and found that age (p = 0.027), sex (p < 0.001), APOE gene (p = 0.007) and glomerular filtration rate (GFR) estimated by the Chronic Kidney Disease Epidemiology Collaboration creatinine equation (CKD-EPI eGFRCr) (p = 0.002) were related to sUA (Figure 1). Here, APOE is linked to chronic kidney disease.
