Fig. 5From: Analysis of hydration and subchondral bone density on the viscoelastic properties of bovine articular cartilageMean stiffness as a function of the Natural log(frequency) for (a) Storage stiffness and (b) loss stiffness of cartilage samples at three different hydration levels; RH-100% (black circles), RH-30% (red squares), and RH-1% (cyan triangles). Mean values have been calculated from n = 16 samples. Error bars show 95% confidence intervals for N = 8 independent samples, blue lines show 95% condidence intervals for the lines of regression for N = 8 independent samplesBack to article page
