Fig. 4From: Analysis of hydration and subchondral bone density on the viscoelastic properties of bovine articular cartilageMass of cartilage samples measured after 24, 48, 72, and 120 h. Control samples (black triangles, dashed line) were kept in an RH of 100%, whilst other samples were dehydrated in a step-wise manner from 100 to 30% to 1% every 24 h (red circles, solid line) before being kept in RH 1% for a further 48 h to fully dehydrate. Error bars show 95% confidence interval for N = 8 independant samplesBack to article page
