ALB and anemia: Additionally, it was illustrated that PAR was a novel marker for ESRD in IgAN patients with proteinuria≥1.0 g/d (P=0.031, Figure 5B), CKD 3-4 (P=0.005, Figure 5D), normal blood pressure (P=0.008, Figure 5E), hypertension (P=0.050, Figure 5F), Alb>30 g/L (P=0.003, Figure 5G), and anemia (P=0.003, Figure 5J), showing that PAR was more suitable for forecasting in these situations.
