Logistic regression analysis for prevalence of sarcopenia, low LTI, and low HGS

Variable	Cystatin C/creatinine ratio (per 1 increase)
	Unadjusted		Model 1		Model 2		Model 3
	OR (95% CI)	p-value	aOR (95% CI)	p-value	aOR (95% CI)	p-value	aOR (95% CI)	p-value
Sarcopenia	5.39 (2.53–11.50)	<0.001	2.33 (1.06–5.15)	0.04	2.62 (1.13–6.08)	0.02	4.60 (1.67–12.68)	0.003
Low LTI	10.34 (4.62–23.15)	<0.001	4.57 (2.00–10.41)	<0.001	4.72 (1.96–11.35)	0.001	7.18 (2.56–20.17)	<0.001
Low HGS	6.92 (3.27–14.65)	<0.001	2.11 (0.98–4.56)	0.06	2.02 (0.90–4.53)	0.09	2.59 (1.01–6.64)	0.048

Model 1: adjusted for age and body mass index. Model 2: adjusted for model 1 plus diabetes mellitus and hypertension. Model 3: adjusted for model 2 plus albumin, hemoglobin, and estimated glomerular filtration rate.

aOR, adjusted odds ratio; CI, confidence interval; HGS, handgrip strength; LTI, lean tissue index.
