  • HR, hazard ratio; 95% CI, 95% confidence interval; PS, propensity score.

  • a Adjusting for age, sex, body mass index, systolic BP, use of antihypertensives, serum concentration of creatinine, urinary protein, and initial dose of PSL at initiation of mPSL+PSL and PSL.

  • b Cox proportional hazards models stratified by 42 matched pairs.
