Odds ratios for LS by the IGF-1 value

	Odds ratio	95% CI	p
Model 1
IGF-1(− 1 ng/ml)	1.019	1.002, 1.039	0.027
Model 2
IGF-1 (< 82 ng/mL)	2.275	0.993, 5.324	0.052

The multiple logistic regression analysis was adjusted by presence or absence of osteoporosis and osteoarthritis, and propensity score estimated from sex, age, and BMI

The explanatory variable is the numerical value of IGF-1 in Model 1, and the nominal variable with IGF-1 < 82 in Model 2
