Distribution of the incidence of renal impairment after surgery between concomitant CMP-IV (n=308) and no AF surgery (n=308) groups after propensity score matching. Renal impairment was evaluated by clinical severity: acute kidney injury, renal failure, dialysis, and dialysis at discharge. Absolute numbers can be found in Table 2.
AF, atrial fibrillation; AKI, acute kidney injury; CMP-IV, Cox-Maze IV.
