In patients with an abnormal %CBF reduction, the relationship was highly significant: %CBF reduction = 0.971 × %CO reduction − 1.027; R 2 = 0.762; p < 0.001.
In patients with an abnormal %CBF reduction, the relationship was highly significant: %CBF reduction = 0.971 × %CO reduction − 1.027; R 2 = 0.762; p < 0.001.
In HCs, the slope was marginally significant: %CBF reduction = 0.171 × %CO reduction − 4.708; R 2 = 0.114; p = 0.018.
