Strain rates normalized by the initial weight of bone specimens () versus the mass of trabecular bone removed (top horizontal axis: absolute mass in grams; bottom horizontal axis: normalized by the total mass of femoral trabecular bone in percent, W). Data point and error bar at W = 0 indicate the mean and standard error of measurements for 3 control specimens. Other data points indicate individual trials. A sigmoid function of the form (where a,b,c,k are empirical constants) was fitted to the experimental data.
