Creatinine- and Cystatin C-Based Incidence of Chronic Kidney Disease and Acute Kidney Disease in AKI Survivors

Table 5

Logistic regression model presenting odds ratios for estimates of CKD (GFR under 60 mL/min/1.73 m²) according to cystatin C at follow-up analysis weighted for the risk of death before follow-up. Follow-up was between 2 and 7 months. The probability of CKD was according to CKD-EPI cystatin C-based eGFR <60 ml/min/1.73 m² at follow-up.
