Table 4

Odds ratio (OR) and 95% confidence interval (95% CI) of ACTN3 genotype for sarcopenia.

Genotype	OR1 (95% CI)		OR2 (95% CI)
RR versus RX	1.212 (0.664–2.213)	0.530	1.136 (0.595–2.168)	0.699
RX versus XX	1.696 (.938–3.065)	0.080	2.020 (1.045–3.904)	0.037
RR versus XX	2.056 (1.024–4.127)	0.043	2.237 (1.044–4.836)	0.038
Dominant	2.056 (1.024–4.127)	0.043	1.401 (0.760–2.582)	0.279
Recessive	2.056 (1.024–4.127)	0.043	1.970 (1.070–3.629)	0.029

CI: confidence interval; OR: odds ratio; dominant: RR versus RX + XX; recessive: RR + RX versus XX; OR₁ and : unadjusted; OR₂ and are adjusted for age, gender, body fatness, and vitamin D.
