ALB and hyperuricemia: Multivariate regression analysis revealed that hyperuricemia (HR=2.20, 95%CI 1.26 to 3.86), proteinuria (HR=2.16, 95%CI 1.47 to 3.18), significantly lower serum albumin (HR=2.34, 95%CI 1.51 to 3.68) and eGFR (HR=1.96, 95%CI 1.47 to 2.61), older age (HR=1.85, 95%CI 1.28 to 2.61), and higher levels of sPLA2R-ab (HR=2.08, 95%CI 1.43 to 3.18), were independent predictors of renal progression in PMN patients (Table 3).
