Figure 6

Concentration of cortisol between the NPOD and POD groups.

Notes: There were no significant differences in the cortisol levels between the two groups prior to surgery (T0) (P=0.15). At the end of surgery (T1) and 12 h after surgery (T2), the cortisol levels were higher in the POD than that in NPOD group (P<0.01). At T1 and T2, the levels of cortisol in each group were higher than those in the corresponding group at T0 (P<0.05).

Abbreviations: NPOD, no POD; POD, postoperative delirium; h, hours.
