Relationship between serum estradiol concentration and bone mineral density in lumbar vertebra, femur and distal radius.

Table 1: Relationship between serum estradiol concentration and bone mineral density in lumbar vertebra, femur and distal radius.

	Serum estradiol concentration
	ρ	p-value
Lumbar vertebra	0.45	0.082
Femoral neck	0.53	0.034
Distal radius	0.69	< 0.001

Spearman's correlation coefficients between bone mineral density and serum estradiol concentration were calculated in the athlete group as a pilot study.
