Pearson correlation coefficient and Spearman correlation coefficient are given with the level of significance in parentheses. Significant correlations are highlighted (P < 0.05). n.e. not evident because one of the variables is constant (error rate = 0). RFL: right forelimb, LFL: left forelimb, RHL: right hind limb, LHL: left hind limb, B: baseline, PI 7: post-ischemic day 7, PI 28: post-ischemic day 28.
