Evolution of biologic and histologic characteristics COL4A3-cIgAN (P1‒P4) between onset and last follow-up (before kidney transplantation). (a) Serum albumin at onset and last follow-up. (b) Proteinuria at onset and last follow-up. (c) Estimated glomerular filtration rate (eGFR) at onset and last follow-up. (d) Evolution of histologic lesions. (e) Table of clinical, biologic, and histologic characteristic of COL4A3-cIgAN. For quantitative variables, values are expressed as median [interquartile range]. For qualitative variables, values are expressed as number (%). C1/C2, presence of extracapillary proliferation; E1, presence of endocapillary hypercellularity; M1, presence of mesangial hypercellularity; S1, presence of segmental glomerulosclerosis or adhesion; T1, presence of tubular atrophy/interstitial fibrosis.
