Systolic blood pressure as a function of age. Systolic blood pressure was higher among patients with hemophilia (PWH) compared to men of the general United States population (NHANES) at all ages, whether or not the subjects were taking antihypertensive medications. PWH are shown by solid lines and NHANES subjects by broken lines. Tenth percentiles, medians, and 90th percentiles are shown. The lower percentile lines show the 10th, while the upper percentile lines show the 90th. (a) Systolic blood pressure for untreated subjects. (b) Systolic blood pressure for treated subjects (taking antihypertensive medications).
