Table 5.
Systolic blood-pressure values and secondary forms of hypertension in the study participants. Measurements during the physical examination in the sitting position and during ABPM are shown. Dipping is defined as a night-time drop in blood pressure > 10% of the daily mean. Shown in each case is the median (Q1–Q3) or the percentage. p > 0.05, * p ≤ 0.05, and *** p < 0.001 compared to control. °° p < 0.01, and °°° p < 0.001 compared to HypWell.
