Incidence and severity of AKI in RTRs versus non-RTRs. (A) AKI event rates in RTRs versus non-RTRs. (B and C) Unadjusted and adjusted ORs for any AKI (B) and severe AKI (C). ORs depict the risk of AKI according to renal Tx status (RTR versus non-RTR), age (per 10 years), preop eGFR (per 10 mL/min/1.73 m²) and CPB time (per 10 min). ^aStage 2 or 3 AKI includes patients who required dialysis. ^bMultivariable models included the following variables: renal transplant (RTR versus non-RTR), age, preop eGFR and CPB time.
