From: Sex-specific associations between muscle-fat ratio and bone density in middle-aged adults

Subgroup analysis of the correlations of skeletal muscle mass, visceral adipose tissue area and their ratio with lumbar bone mineral density. Age, sex, race, educational level, marital status, sedentary behavior, history of hypertension, history of diabetes, body mass index, total protein, blood urea nitrogen, serum calcium, serum glucose, triglycerides and total cholesterol were adjusted. In the subgroup analysis, the model is not adjusted for the stratification variable itself. SMM: skeletal muscle mass VATA: visceral adipose tissue area SVR: skeletal muscle mass to visceral adipose tissue area ratio.
