Figure 1: Histogram showing the frequency of absolute differences in BMD between left and right femoral neck (a), trochanter (b), and total hip (c). Numbers above the bars are the number of left-right hip pairs with the difference indicated on the abscissa. The SDD is shown as the vertical line; bars to the right show the number of hip pairs in which the left-right difference exceeded the SDD.
