Anemia is a common complication of chronic kidney disease (CKD) and is associated with faster renal function decline and adverse clinical outcomes. However, its prognostic value in IgA nephropathy (IgAN) and potential sex-specific differences remain unclear. This study aimed to evaluate the association between hemoglobin (Hb) levels and the risk of progression to end-stage kidney disease (ESKD) in patients with IgAN.
