Comparison of blood pressure and adherence outcomes between the control and the intervention group during the first 6 months of follow-up.

Repeated BP Measures (1, 3 & 6 Months visits)* Unadjusted Analysis Adjusted analysis

Intervention (n=418) Control (n=457) Intervention (n=417) Control (n=453)
SBP mmHg [mean (SE)] 149.7 (0.82) 151.1 (0.70) 148.9 (0.69) 151.1 (0.57)
Uncontrolled SBP >= 140 mmHg (%) 65.6 73.3 66.6§ 76.3
Uncontrolled SBP >= 140 mmHg [OR (95% CI)] 0.70 (0.56, 0.87) 1.00 (Ref. group) 0.62 (0.50, 0.78) 1.00 (Ref. group)
DBP mmHg [mean (SE)] 82.8 (0.49) 82.3 (0.42) 81.9 (0.35)|| 83.0 (0.30)
Uncontrolled DBP >= 90 mmHg (%) 26.1 22.4 18.1 19.0
Uncontrolled DBP >= 90 mmHg [OR (95% CI)] 1.22 (0.97, 1.55) 1.00 (Ref. group) 0.94 (0.73, 1.20) 1.00 (Ref. group)
6 Month Cumulative main Adherence Outcomes Intervention (n=374) Control (n=423) Intervention (n=332) Control (n=377)
 Adherence, % days correct dose taken [mean (SE)] 91.2 (0.11)|| 88.2 (0.09) 92.2 (0.09) 89.0 (0.07)
 Adherence, % of patients with at least 80% adherence 88.2 83.5 91.9 85.6
 Adherence ≥ 80% [OR (95% CI)] 1.49 (0.87, 2.54) 1.00 (Ref. group) 1.91 (1.19, 3.05) 1.00 (Ref. group)
*

Analysis for BP outcomes were adjusted for geographic area (Catalonia versus Madrid), number of risk factors, body mass index, age, and the baseline level of the outcome variable.

Analysis for adherence outcomes were adjusted for baseline diastolic blood pressure, geographic area, self-reported measure of adherence at baseline, self-reported measure of not showing up at the scheduled doctor visits.
