Trajectories of long-term eGFR and proteinuria in lupus nephritis: a real-world biopsy-proven cohort study

Distinct long-term trajectories of eGFR and proteinuria exist in LN. Short-term responses in eGFR and proteinuria may not reliably predict long-term renal outcomes, highlighting the need for more robust biomarkers to improve risk stratification and management in LN.
