Histological findings were scored semiquantitatively by using the following criteria: 0: absent; 1: mild; 2: moderate; and 3: prominent. DM, data missing; GBM, glomerular basal membrane; IgA, immunoglobulin A; IgG, immunoglobulin G; K, light chain Kappa deposits; L, light chain Lambda deposits; RBC, red blood cells.
