(A) Forest plot for systolic blood pressure (n = 6). Notes: Sub-group analysis based on methods used for blood pressure assessment (1–24 h mean, 0-cross-sectional); overall weighted mean difference (WMD) = −2.9 mm/Hg, z = 1.13, P = 0.26; WMD for Group 0 = 0.2 mm/Hg, z = 0.08, P = 0.94; WMD for Group 1= −7.8 mm/Hg, z = 5.25, P < 0.001. (B) Forest plot for diastolic blood pressure (n = 6). Notes: Sub-group analysis based on methods used for blood pressure assessment (1–24 h mean, 0-cross-sectional); overall weighted mean difference (WMD) = −1.6 mm/Hg, z = 1.22, P = 0.22; WMD for Group 0 = 0.6 mm/Hg, z = 0.86, P = 0.39; WMD for Group 1 = −4.2 mm/Hg, z = 3.43, P = 0.001.
