Table 4

Comparison of 48 h operation rate, preoperative waiting, hospital stay, incidence of postoperative delirium, and ADL score between the CGA group and the general group.

Classification	CGA group	Study group	χ ^2/Z	P value
48 h operation rate (cases, %)	23 (32.9)	10 (11.8)	χ ^2 = 22.153	≤0.001^a
Preoperative waiting (d)	5.9	8.7	Z = −6.387	≤0.001^b
Hospital stay (d)	20.8	23.6	Z = −11.756	≤0.001^b
Incidence of postoperative delirium (%)	15 (21.4)	27 (31.8)	χ ^2 = 23.897	≤0.001^a
ADL score (score)	50.5	51.7	Z = −0.640	0.522^b
