Fig. 3From: NGAL expression during cardiopulmonary bypass does not predict severity of postoperative acute kidney injuryCorrelation of uNGAL concentrations to corresponding AKIN levels on postoperative days 2, 4, 6, 8, and 10. The scatter-plots show uNGAL values at Tp1 and Tp2. A good prognostic valence is given if the values were mostly in the left upper half of the diagram (shadow area of index chart “expected range”)Back to article page
