Prevalence and Risk Factors of Discordance between Left- and Right-Hip Bone Mineral Density Using DXA

Table 3

Percent of cases in which the left-right hip subregion exceeded the SDD with patients sorted by age.

		Femoral neck (%)	Trochanter (%)	Total hip (%)
Age	50–65 years (𝑛=1647)	815 (49.5)	945 (57.4)	844 (51.2)
	>65 years (𝑛=712)	401 (56.3^*)	440 (61.8^*)	415 (58.3^*)

^*Significantly greater than for 50–65-year group, Chi-square, 𝑃<0.01 or less.
