The Effect of Chunghyul-Dan on Hyperventilation-Induced Carbon Dioxide Reactivity of the Middle Cerebral Artery in Normal Subjects: A Dose-Dependent Study

Figure 4

Pearson’s correlation analysis of the changes in CO2 reactivity and CV40 before and after CHD administration. A significant correlation is shown between CHD administration-mediated changes in CO2 reactivity and the CV40 of the MCA (, ).
