Comparison L1–L4 and femoral BMD values with the DEXA results according to work experience

Bone type	Work experience (years)	N	T-score	P-value
L1–L4	10–19	32	−1.02±0.55	0.255*
	20 and older	15	−1.36±0.76
Femur	10–19	32	−0.44±0.28	0.021*
	20 and older	15	−0.94±0.51

Notes:

^*Independent t-test was applied. Bold P-value defines the significant difference (P<0.05). The data were given as mean ± standard deviation.

Abbreviations: BMD, bone mineral density; DEXA, dual-energy X-ray absorptiometry.
