Immunosuppressive strategies for renal function preservation in IgA nephropathy with partial crescent formation: A retrospective cohort study

Despite more severe baseline disease, the P+CTX regimen was associated with a greater reduction in proteinuria in IgAN patients with minor crescent formation. It is important to note, however, that causal inference was limited by residual confounding. Despite adequate short-term safety, extended follow-up is mandatory to fully evaluate the long-term complications of CTX.
