Figure 1. (A) Difference in systolic and diastolic blood pressure changes; (B) frequency of blood pressure normalization; and (C) impact on secondary outcomes of home blood pressure telemonitoring compared to usual care in different meta-analyses of randomized controlled studies. Data are shown as mean difference or relative risk and corresponding 95% confidence interval. The type of intervention in the various meta-analyses was commonly mixed, though a few publications focused on interventions relying exclusively on m-health. The length of the observation was always greater than 6 months. SBP: Systolic blood pressure; DBP: diastolic blood pressure; BP: blood pressure. Updated and redrawn with permission^[11].
