Official Title: The Risk of Uncomplicated Peptic Ulcer in a Cohort of Secondary Prevention Aspirin Users
Brief Summary:
This study is conducted in a cohort of low dose aspirin (ASA) users previously ascertained. The aims of the post hoc analyses are:
To estimate the incidence of uncomplicated peptic ulcer (UPU) in a cohort of low-dose ASA for secondary prevention of vascular disease and the relative risk of UPU associated with use and discontinuation of use of low dose ASA.
