Data from [6]. HBPM, home BP, one set of measurements is the average of two duplicate self-measurements taken twice daily over 6 days.
On the basis of coefficients of variation reported in Warren et al.[15].
Percentages do not add to 100% as excludes 24.1% of adult population who are taking BP lowering medication.
OBPM, office BP, one set of measurements is the average of 2 duplicate clinic measurements, repeated after 6 weeks.
ABPM, ambulatory BP, one set of measurements is the average of ambulatory BP measurements taken over 12 h (daytime).
