The corresponding difference between the awake ambulatory blood pressure and manual office blood pressure for the first post-enrolment office visit in the control group was −6.5 (−4.3 to −8.6 /−4.3 (−2.9 to −5.8) (P<0.001/P<0.001) (table 2).
*Estimated between group mean difference from post-enrolment manual office diastolic BP (r=0.30) was 0.26 (0.09 to 0.41); P<0.411.
All interviews except at enrolment took place at the client's home or, if this was not possible, at the social science office.
Upon receipt of the consent and enrolment form by the research office, random allocation to the intervention or control group will be conducted by an individual who is independent to the study by drawing opaque numbered envelopes consecutively, to reveal the group allocation.
In the control group, routine manual office blood pressure before enrolment (149.9 (10.7)/81.8 (8.5)) was reduced to 141.4 (14.6)/80.2 (9.5) after enrolment (P<0.001/P=0.01), but the reduction in the intervention group from manual office to automated office blood pressure was significantly greater (P<0.001/P=0.02).
Both the patients in this study and those in CAMBO were recruited from primary care practices in the community, and routine manual office blood pressure readings before enrolment were similar in the two studies.
The study office administrative staff dealt with the enrolment of the participants and automatically assigned them to two groups based on the Excel file.
Enrolment entails visits to admission services, the SIS office, the pharmacy and a self-funded echography to prove pregnancy, unless the pregnancy is obvious.
This is supposed to cover all recurrent costs of enrolment, triage and the visit to the ANC office, including rapid tests and iron supplements but excluding all salaries and capital costs [ 14].
Manual office blood pressure readings taken before enrolment were significantly higher than the awake ambulatory blood pressure, which is considered to be a gold standard for defining blood pressure status.
The Women's Council and the First Lady's office have been instrumental in driving girls' enrolment rates up.
