Table 2. The association between preoperative CMB and occurrence of POD and POCD.

	Patient without CMB (n = 48)	Patients with CMB (n = 17)	OR (95% CI)	P value
POD	12 (25%)	2 (12%)	0.278 (0.049, 1.565)	0.147
POCD 7 days after surgery*	8 (21%)	3 (19%)	0.761 (0.164, 3.535)	0.727
POCD 3 months after surgery*	2 (7%)	1 (10%)	0.606 (0.032, 11.637)	0.740

*calculated for 54 patients with POCD assessment after 7 days and 40 patients with POCD assessment after 3 months. Frequencies with n (%); CI, confident interval; OR, odds ratio; POD, postoperative delirium; POCD, postoperative cognitive dysfunction.
