The changes in the estimated glomerular filtration rate and the number of events in the overall patients and patients with classified renal disorders.

<p>Abbreviations: eGFR, estimated glomerular filtration rate (mL/min/1.73 m²); GN, glomerulonephritis; MC, minimal change; MN, membranous nephropathy; N, nephropathy; RB, renal biopsy; RRT, renal replacement therapy. A composite renal event was defined as a decline in the eGFR of more than 30% of the baseline value, initiation of RRT or death associated with a renal disorder. The values are expressed as the means ± SD.</p>a<p><i>P</i><0.01 versus patients with RB.
