BMI: body mass index; BUA: broadband ultrasound attenuation; SOS: speed of sound; IMT: intima-media thickness; 25OHD: 25-hydroxy vitamin D. Data are median (1st–3rd quartiles) or proportions. Group differences were tested with the Kruskal-Wallis or chi-squared tests. 25OHD: men—1013 missing, women—1127 missing. Self-reported osteoporosis: men—51 missing, women—63 missing.
