A Radiographic Study on the Associations of Age and Prevalence of Vertebral Fractures with Abdominal Aortic Calcification in Japanese Postmenopausal Women and Men

Table 2

Characteristics of the study subjects according to the presence of abdominal aortic calcification.

	Aortic calcification		$P$-va1ue
	Present	Absent
$N$	175	226
Men/Women	11/164	13/213	NS
Age (years)	75.9 $\pm$ 6.1	72.2 $\pm$ 8.0	$<$.0001
Number of subjects with a history of hip Fx	7	2	$<$.05
Number of subjects with $\ge$1 prevalent vertebral Fxs	129	92	$<$.0001
Number of prevalent vertebral Fxs	2.20 $\pm$ 2.47	0.97 $\pm$ 1.90	$<$.0001
Spondylosis grade	1.40 $\pm$ 0.63	1.34 $\pm$ 0.70	NS
Severity of calcification (Indicated by the number of the vertebral bodies)	3.10 $\pm$ 1.62	0.00 $\pm$ 0.00	$<$.0001

Data are expressed as the mean $\pm$ standard deviation (SD). Data comparisons between two groups were performed using an analysis of variance (ANOVA) with Fisher’s protected least significant difference (PLSD) test. Fx: fracture; NS: not significant.
