Association between ASMI and total lumbar BMD.

ASMI (kg/m2)	Total lumbar spine BMD (g/cm2)

Model 1: Adjusted for age, race, serum calcium level, creatinine, albumin, total fat ratio, serum potassium, phosphorus, and diabetes status; Model 2: Adjusted for age, serum potassium, albumin, and total fat ratio.

ASMI = appendicular skeletal muscle mass index, BMD = bone mineral density, SE = standard error.
