Exacerbation	6.05 (1.18–43.6)	0.031	14.4 (1.87–145.6)	0.011
Test for trend		0.011		0.006

NOTE: HR, hazard ratio; CI, confidence interval.

Data are the HR, 95% CI, and P-value from Cox proportional hazard regression analyses. This analysis is based on data from 100 patients because the decrease rate of proteinuria was missing for one patient. Adjusted for baseline characteristics (age, sex, systolic/diastolic pressure, serum albumin level, serum creatinine level, urinary protein, use of immunosuppressive therapy, initial dose of PSL (mg)/day, 25% decrease of proteinuria within 1 month after initial immunosuppressive therapy).
