Characteristics of the patients.

*The ages of patients with healed CresGN, CresGN, MN, or nephrosclerosis were significantly higher than those of the other groups (P<0.01) except for the patients with TIN. The ages of patients with healed CresGN and CresGN were significantly higher than those of patients with with TIN at P<0.05. The age of patients with IgAN was significantly lower than that of patients with non-IgA mesPGN, FSGS, or TIN and that of healthy volunteers at P<0.01 and was significantly lower than that of patients with MPGN and MCNS at P<0.05. †Patients with MCNS and MN had significantly heavier proteinuria compared with patients with IgAN, non-IgA mesPGN, AGN, nephrosclerosis, or TIN at P<0.01 and patients with MPGN or CresGN at P<0.05. Patients with FSGS manifested heavier proteinuria than patients with IgAN at P<0.01 and patients with non-IgA mesPGN, nephrosclerosis, or TIN at P<0.05. gCr indicates gram of urinary creatinine. ‡For the estimated glomerular filtration rate (eGFR), patients with CresGN had a significantly lower eGFR than did patients with healed CresGN (P<0.05) and the other patients (P<0.01) except those with TIN. Patients with TIN had a significantly lower eGFR than did the other groups except patients with CresGN or healed CresGN. Patients with healed CresGN had a significanty lower eGFR than the other patients except those with CresGN, nephrosclerosis, or TIN. Healthy volunteers had significantly higher eGFR values than the other groups except patients with IgAN, non-IgA mesPGN, AGN, MCNS, or MN. Patients with FSGS and MPGN had significantly lower values than did healthy volunteers, and patients with FSGS had a significantly lower value than did patients with IgAN at P<0.05. §Negative proteinuria results were obtained via the test tape method.
