Abstract
Considering both published and unpublished studies, we observed an effect of IHT on awake diastolic BP (MD = −2.02; 95% CI, −3.89 to −0.15 mmHg; P = .03). There were no significant effects on 24-hr systolic BP (MD = −1.31; 95% CI, −3.84 to 1.22 mmHg; P = .31), asleep systolic BP (MD = −0.84; 95% CI, −3.31 to 1.63 mmHg; P = .50), awake systolic BP (MD = −0.93: 95% CI, −3.10 to 1.23 mmHg; P = .40), 24-hr diastolic BP (MD = −0.96; 95% CI, −2.65 to 0.74 mmHg; P = .27), or asleep diastolic BP (MD = −1.27; 95% CI, −3.22 to 0.67 mmHg; P = .20). In conclusion, the effects of IHT on ambulatory BP were observed primarily in awake diastolic BP among individuals over 18 yr of age.
