Across 3 studies, 1 reported a beneficial small effect on reduced diastolic blood pressure, while 2 found neutral effects. The single beneficial study was a systematic review and meta-analysis showing a statistically significant reduction of -2.20 mm Hg (95% CI: -4.13, -0.27). Effects were predominantly small in magnitude, and the evidence base is too limited to identify a clear dose range or population.
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests.
or diastolic blood pressure (DBP) (reduction of 0.46 mmHg; 95% CI: -2.80, 1.87; I² = 0%)
A significant decrease in diastolic blood pressure (DBP) was also observed (MD: -2.20 mm Hg; 95% CI: -4.13, -0.27; I2 = 11%)
Pooled results revealed statistically non-significant reductions of -0.15 mm Hg for DBP (95% CI: -1.36, 1.05; I² = 27%)
