Regression analysis of the percent differences of all parametric MRI relaxation constants and of the light absorption between the viable and necrotic epiphyseal cartilage.

<p>The solid line shows the linear fitting (R² = 0.39) between the percent differences of all MR relaxation constants (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0140400#pone.0140400.t004" target="_blank">Table 4</a>) and the percent difference of the light absorption (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0140400#pone.0140400.t002" target="_blank">Table 2</a>, column 4), resulting in the slope equal to 0.21.
