Fig. 1From: Quantitative ultrasound assessment of the effect of parity on bone mineral density in femalesComparison of the mean broadband ultrasound attenuation (BUA) value, as assessed by an ultrasound-based bone densitometer, of females who had no pregnancies (nulliparous) with the mean BUA of females in the multiparous group. The mean BUA is higher in the nulliparous group reflecting a higher bone mineral density in this group as compared to the multiparous groupBack to article page
