Differences in CVR amplitude and time delay were assessed among patients with hypertension (HT), hypertension-plus-type-2 diabetes (HT+DM), and age-matched controls (CTL) using a pipeline for adaptive capturing of the BH response directly from BOLD data, ensuring greater robustness. The lowest CVR amplitude and the longest delay were found in the HT+DM group. CTL had the highest CVR amplitude, and the HT group had the shortest time delays. CVR delay was more sensitive to group differences than amplitude.
