Table 5. Comparison of the aortic diameter of female patients.

Variables	Aortic dissection (n=43)	Ascending aortic dilation (n=31)	P value
Aortic sinus diameter, mm	34.57±3.48	33.92±4.19	0.509
Ascending aortic diameter, mm	53.81±10.84	54.90±7.47	0.631
Ascending aortic diameter indexa	30.58±6.56	32.03±4.37	0.288

^a, ascending aortic diameter index means the ratio of ascending aortic diameter divided by body surface area.
