BMD: bone mass density; L: lumbar; ASM: appendicular skeletal muscle mass; the Bonferroni critical value () was used for statistical significances of BMDs and -scores by dividing by the number of tests ().
denotes that XX homozygotes were significantly different compared to RR homozygotes. # denotes that XX homozygotes were significantly different compared to RX heterozygotes.
