Correlations between predicted and measured CBF for the above four experiments.
<p>Due to cross-validation and the number of the various measurements available, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0165536#pone.0165536.t002" target="_blank">Table 2</a>, the number of data points used to learn the models vary.</p
