Estimated hazard ratios (HR) and 95% confidence intervals (Cl) from Cox proportional hazards model of time to primary outcome for select average daily dose combinations of strategy drugs, relative to atenolol 50 mg/d in the atenolol‐based treatment strategy, from a model adjusted for average follow‐up systolic blood pressure (SBP) and diastolic blood pressure (DBF). SR=sustained‐release; HCTZ=hydrochlorothiazide; “'ratio with a value ranging from 0 to 1 that represents the amount of time specific verapamil SR/trandolapril or atenolol/HCTZ dose combinations were prescribed simultaneously; **HR (95% CI) has been adjusted for average SBP and DBP.
