  1. We asked contact persons to code the following situation:
  2. Biopsy: 15 glomeruli, 1 cellular crescent, 2 lesions of segmental glomerulosclerosis, 4 lesions of global glomerulosclerosis. Tubular atrophy in around 20% of the cortical area. Moderate arteriolosclerosis and arteriolosclerosis. IH: dominant IgA positivity. Diagnosis: mesangioproliferative glomerulonephritis; IgA nephropathy; Oxford classificaion: M1 E0 S1 T0 C1
  3. Data are depicted literally as mentioned by the registry contact persons
