Diagnostic concordance between the TBS and LS-BMD in classifying women positive or negative by analyzing women with and without fractures separately (K Cohen test).

	Women with Fractures			Women without Fracturs
	TBS Positive %	TBS Negative %	Total %	TBS Positive %	TBS Negative %	Total %
LS-BMD Positive test	48.8	18.6	67.4	27.9	14.0	41.9
LS-BMD negative test	23.3	9.3	32.6	17.1	41.0	58.1
Total	72.1	27.9	100	45.0	55.0	100

K Cohen for the women with fractures = 0.010 (poor concordance). K Cohen for the women without fractures = 0.367 (poor concordance).
