Effects of Soluble Fiber on Blood Pressure: A Meta-analysis of Randomly-controlled Trials

The present study conducted a meta-analysis of 22 randomly controlled trials to assess the effects of soluble fiber intake on blood pressure in human subjects.

Using the Cochrane Handbook for Systematic Reviews of Intervention, a systematic review and meta-analysis was conducted. Information regarding study methods, characteristics, mean BP and standard deviations were extracted The data from each study were pooled using a random effects model to estimate the effects of soluble fiber consumption on blood pressure.
