Review/Meta-analysis	Effects on Adherence	Effects on Blood Pressure
Glynn et al,65 2010	• Not assessed	• WMD SBP: −2.5 mm Hg, 95%  CI −3.7 to −1.3 • WMD DBP: −1.8 mm Hg, 95%  CI −2.4 to −1.2
Bray et al,70 2010	• Not assessed	• WMD SBP: −3.8 mm Hg, 95%  CI −5.6 to −2.0 • WMD DBP: −1.5 mm Hg, 95%  CI −2.0 to −0.9
van Dalem et al,53  2012	• Contradictory results  (2 studies)	• Mean DBP: “significant  decrease” (2 studies; data not  reported)
Uhlig et al,71 2013	• “A few studies” found effect  (data not reported)	Self-monitoring only • WMD SBP, 6 mo: −3.9 mm Hg,  P<.001 • WMD DBP, 6 mo: −2.4 mm Hg,  P<.001 • WMD SBP, 12 mo: −1.5 mm Hg,  P>.05 • WMD DBP, 12 mo: −0.8 mm Hg,  P>.05 Self-monitoring + additional  support • Net difference SBP, range, 12 mo:  −8.9 to −2.1 mm Hg • Net difference DBP, range,  12 mo: −4.4 to 0.0 mm Hg
Fletcher et al,52 2015	• d = 0.21 (95% CI 0.08–0.34)	• WMD SBP: −4.1 mm Hg, 95% CI  −6.7 to −1.4 • WMD DBP: −2.0 mm Hg, 95% CI  −2.9 to −1.1
