Renal function parameters of patients with AKI and without AKI.

Parameter	AKI n = 36	no AKI n = 18	P-value
Preoperative renal function
s-Creatinine, μmol/L	66 ± 3	68 ± 4	ns, .72
eGFR, mL/min/1.73 m2	106 ± 3	99 ± 4	ns, .16
Postoperative renal function (most severe renal impairment within 48 hours after surgery)
s-Creatinine (max.), μmol/L	138 ± 9	86 ± 7	<.01
s-Creatinine increase (max.), factor	2.1 ± 0.1	1.3 ± 0.1	<.001
eGFR (min.), mL/min/1.73 m2	64 ± 5	92 ± 6	<.01
Renal function at the day of MRI (14 ± 2 days after lutx)
s-Creatinine, μmol/L	89 ± 10	64 ± 4	ns, .09
eGFR, mL/min/1.73 m2	91 ± 4	106 ± 4	<.05

Significant differences between groups of patients with and without AKI are given in the last column.

AKI = acute kidney injury, CKD = chronic kidney disease, eGFR = estimated glomerular filtration rate, lutx = lung transplantation, MRI = magnetic resonance imaging, ns = not significant.
