Fig 2. Urinary levels of markers for renal injury in patients with and without acute kidney injury after cardiac surgery.
A: Albumin; B: Kidney Injury Molecule-1 (KIM-1); C: N-acetyl-β-D-glucosaminidase (NAG). AKI: acute kidney injury. Time points are before (pre-op) and at the end of the operation (end-op), after 3 hours in the intensive care unit (3h ICU) and on the first and second post-operative day (day 1 and day 2). P-values are given for differences between the groups (# Pgroup) and differences in time (Ptime). using two-way ANOVA with repeated measurements.
