Characteristics of 185 IgAN patients with follow up data stratified by steroids/CTX.

Data are presented as mean ± SEM or median (inter-quartile range [IQR]) for continuous variables and proportions for categorical variables. MAP: Mean arterial blood pressure; UP: Urinary protein; UUMOD: Urinary uromodulin; TA-MAP: Time-average blood pressure; TA-proteinuria: Time-average proteinuria. ACEi: Angiotensin I Converting Enzyme Inhibitor. ARB: Angiotensin receptor blocker. CTX: Cyclophosphamide. eGFR was calculated with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation [15]. eGFR decline rate: was obtained by fitting a straight line through the calculated eGFR using linear regression and the principal of least squares for every patient [13].
