Models were adjusted for baseline orthostatic hypotension and the following baseline characteristics: age, sex, race, treatment assignment, systolic blood pressure, diastolic blood pressure, body mass index, high density lipoprotein cholesterol, total cholesterol, statin use, chronic kidney disease, estimated glomerular filtration rate, subclinical or clinical cardiovascular disease, smoking status, or number of hypertensive medications
