1Study participants with blood pressure values ≥140/90 mmHg and/or antihypertensive medication with known hypertension and/or study participants with risk-comorbidity (diabetes, stroke, angina pectoris, and/or myocardial infarction) and blood pressure values ≥130/80 mmHg.

2OR Odds Ratio.

3CI confidence interval.

4Self reported smoking.

5Both peripheral and central active antiadrenergic substances.

Model 1 considers the active substances the patients received, model 2 considers the kind of therapy (mono or combination therapy). Included are all hypertensive patients1 to SHIP-0 with information on the independent variables to SHIP-1 (N = 1749 of in total 1761 hypertensive patients in the SHIP-0 cohort).
