However, significant associations were presented between free testosterone and locomotor area in model 1 & model 2(0.38, 0.0–0.7, p = 0.04, 0.37, 0.0–0.7, p = 0.04) with borderline significance in model 3 (0.34, − 0.0, 0.7, p = 0.05), respectively (Tables 2 , 3 , 4 ).
No significant associations were found between levels of estradiol and total abdominal and stabilizing muscle radiodensity (Tables 2 , 3 ), but there was a borderline significant association between estradiol and abdominal locomotor muscle radiodensity ((Model 1: 0.27, − 0.0 to 0.6, p = 0.09: Model 2: 0.28, − 0.0 to 0.6, p = 0.07; Model 3: 0.26, − 0.0 to 0.6, p = 0.09) (Table 4 ).
