  1. The separate groups are based on office and ambulatory blood pressure measurement values. Data are shown as mean ± SD or absolute (n) and relative (%, in brackets) frequency. Differences across the four classification groups were all significant (p  < 0.0001)
  2. WCH indicates white coat hypertension, MH masked hypertension, BMI body mass index, OSBP office systolic blood pressure, SBP systolic blood pressure, DBP diastolic blood pressure, HR heart rate, bpm beats per minute, WCE white coat effect (OBPM-24h ABPM). OBPM office blood pressure measurement, ABPM ambulatory blood pressure measurement
