IgG excretion (mg/d)249 (21 to 3082)
eGFR (ml/min per 1.73 m2)50 (25 to 104)
sβ2m (mg/l)3.66 (1.63 to 12.48)
sIgG (g/l)4.34 (1.85−13.35)

  • The data are given as the means ± SD or median (range). Anti-PLA2R, anti-PLA2R antibodies; sCreat, serum creatinine; eGFR, estimated GFR calculated by extended Modification of Diet in Renal Disease formula (MDRD6). The selectivity index (SI) was calculated as IgG clearance/transferrin clearance. SI ≤ 0.2 reflects selective proteinuria, whereas SI > 0.2 is considered nonselective proteinuria.
