  • FSGS, focal and segmental glomerulosclerosis; IgAN, IgA nephropathy; MCD, minimal change disease; MN, membranous nephropathy; eGFR, estimated GFR as calculated by the simplified Modification of Diet in Renal Disease formula: 186×(creatinine [mg/dl])−1.154×(age [years])−0.203×0.742 (if female).

  • a All P values were obtained from one-way ANOVA for testing the equality in population means among the FSGS, IgAN, MCD, and MN groups of patients.
