Abbreviations: BMI, body mass index; CI, confidence interval; HBPM, home blood pressure (BP) monitoring. The reference group is the noncompliant group (HBPM <24 of the 48 weeks). The intervention method (education method and counseling intensiveness) was not adjusted for because there was no significant effect on HBPM.
