Figure 4.

Correlations with clinical status—2 examples. The relationships between measures of clinical performance and 2 physiological parameters are shown, each point representing a patient. (A) There is a significant positive correlation between AH RC gradients in the acute period and ARAT scores at initial assessment (r = 0.754, P = 0.006). (B) SICI in the UH is negatively correlated with NHPT scores when the patients are assessed at 3 months, such that weaker inhibition (i.e., increased excitability to paired pulse TMS) is associated with poor clinical status at this stage (r = −0.686, P = 0.021).
