Figure 3

Relationship between serum cortisol level and incidence of postoperative delirium (POD) after coronary artery bypass graft surgery. Patients with a higher serum cortisol level had a significantly higher incidence of POD (P < 0.001). Level 1 indicates a serum cortisol concentration of less than 138 nmol/L, level 2 indicates a serum cortisol concentration of between 138 and 690 nmol/L, and level 3 indicates a serum cortisol concentration of greater than 690 nmol/L.
