Plots illustrating the derived probabilities of hypertensive status based on the logistic regression model for MWF, R1 and R2. These results are presented for three distinct brainstem subregions: the midbrain, red nucleus, and substantia nigra. Within each plot, red is used to represent hypertensive subjects, while blue corresponds to healthy control subjects. Each plot features centroids represented by solid red and blue dots, which signify both the mean probability of hypertensive classification and the mean value of the respective MRI metric. Surrounding each centroid is a circle that indicates the corresponding standard deviation of the probability classification on the y-axis and the standard deviation of the respective MRI metric on the x-axis. MWF myelin water fraction, R1 longitudinal relaxation rate, R2 transverse relaxation rate
