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

Table 4

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