In the univariate analysis of OxyP, hypertension treatment (other than beta-blocker or angiotensin II receptor blocker (ARB)/angiotensin-converting enzyme (ACE)) (B = -13.2, p = 0.05), warfarin treatment (B = -15.9, p = 0.03) and statin therapy (B = -29.9, p = 0.001), were negatively related to OxyP. This evidence concerns the gene ACE and hypertensive disorder.
