Forest plots of the association between serum creatinine elevation or proteinuria and survival outcomes. (A) Multivariable Cox regression analysis of the association between serum creatinine elevation and progression-free survival; (B) Multivariable Cox regression analysis of the association between serum creatinine elevation and overall survival. (C) Multivariable Cox regression analysis of the association between proteinuria and progression-free survival; (D) Multivariable Cox regression analysis of the association between proteinuria and overall survival.
