Patient Event Sequencing Study Results I: PRESERVE

*- About 56% of patients do not have both events, which in this case, because all patients are known to have a cohort entry date, means that about half the cohort was not prescribed an antihypertensive. - For patients who were prescribed an antihypertensive, about 25% of that group were exposed within a year (either before or after) of their cohort entry date. About 8% were exposed within a month, and 5% were exposed within 2 weeks.
