- They designed a network meta–analysis.
- For this study, randomized controlled trials (RCTs) were retrieved from PubMed and Embase up to June 2016, which are published in English and reported on meditation exercise for hypertensive patients.
- Risks of bias evaluation of the included studies were evaluated by Cochrane Collaboration Recommendations and network meta–analysis was performed by ADDIS.
- Mean difference (MD) and its 95% confidence interval (CI) were utilized as the effect size.
- In this study, total 19 RCTs were included.
- The outcomes of pairwise comparisons showed that meditation exercise could majorly reduce the SBP and DBP, compared with other interventions (MD = –7.10, 95% CI: –10.82 to –3.39; MD = –4.02, 95% CI: –6.12 to –1.92).
- With good consistence and convergence, network meta–analysis demonstrated that there were no important differences between meditation and other interventions on SBP.
- For DBP, Qigong was significantly lower than “no intervention” (MD = –11.73, 95% CI: –19.85 to –3.69).
