highly significantp = 6.5 × 10 −17
Given the highly significant positive association (Spearman’s 0.64, p = 6.5 × 10 −17 ) between hip BMDs and body mass index (BMI) (Supplementary Fig. 2 ); and other BMI-correlated physical parameters, including body weight and waist circumference in this population, we performed additional analyses on the two subgroups based on BMI: 82 lean women with normal BMI (18.5–24.9 kg m −2 ), and 51 obese women with higher BMI (≥25.0 kg m −2 ).
