  • ‡Systolic blood pressure (SBP) and diastolic blood pressure (DBP)—information available for 152 adherent, 52 any non-adherent and 21 completely non-adherent patients.

  • §24 h daytime SBP and DBP—information available for 121 adherent, 26 any non-adherent and 15 completely non-adherent patients, data in columns 2–4 are means and SDs of absolute blood pressure values recorded by clinic measurements and 24 h ambulatory blood pressure monitoring. Beta—β-coefficient, p value—level of statistical significance; all from adjusted linear regression models with blood pressure as dependent quantitative variable and age, sex, ethnicity and clinical category (new referrals, follow-up patients, referrals for renal denervation) as well as non-adherence to antihypertensive treatment as independent parameters included in the model.
