Cox multivariate analysis of patients with and without Shrunken Pore Syndrome. (A) Defined by the equation pair CKD-EPI_{cystatin C} and CKD-EPI_creatinine with a cut-off of 60% (i.e. eGFR_{cystatin C} ≤ 0.6 eGFR_creatinine). (B) Defined by the equation pair CAPA and LMrev with a cut-off of 60% (i.e. eGFR_{cystatin C} ≤ 0.6 eGFR_creatinine). (C) Defined by the equation pair CAPA and LMrev with a cut-off of 70% (i.e. eGFR_{cystatin C} ≤ 0.7 eGFR_creatinine).
