Effects of pomegranate juice on blood pressure: A systematic review and meta-analysis of randomized controlled trials
- A comprehensive literature look in Medline and Scopus was completed to distinguish qualified RCTs.
- A meta–analysis of qualified reviews was performed utilizing a random–effects model.
- Quality assessment, sensitivity analysisand publication bias assessments were led utilizing standard methods.
- Quantitative information synthesis from 8 RCTs indicated significant decreases in both systolic [weighed mean difference (WMD): –4.96 mmHg, 95% CI: –7.67 to –2.25, p < 0.001) and diastolic BP (WMD: –2.01 mmHg, 95% CI: –3.71 to –0.31, p = 0.021) after pomegranate juice intake.
- Consequences for SBP stayed stable to sensitivity investigations.
- Pomegranate juice diminished SBP regardless of the duration (>12 wks: WMD = –4.36 mmHg, 95% CI: –7.89 to –0.82, p = 0.016) and <12 wks: WMD = –5.83 mmHg, 95% CI: –10.05 to –1.61, p = 0.007) and dose consumed (>240 cc: WMD = -3.62 mmHg, 95% CI: –6.62 to –0.63, p = 0.018) and <240 cc: WMD = –11.01 mmHg, 95% CI: –17.38 to –4.65, p = 0.001, pomegranate juice per day) whereas doses >240 cc provided a borderline significant impact in lessening DBP.
