a
Adjusted for factorial design, baseline level, age, sex, practice, length of follow-up and current medication use.
b
Consultations where focus was hypertension or where blood pressure was recorded.
c
Adjusted for factorial design, age, sex and practice.
d
Change to medication defined as alteration to dose, or starting, stopping or swapping any medication. SBP = systolic blood pressure. DBP = diastolic blood pressure. SD = standard deviation.
