C-Comparison: Comparison group Placebo or a similar food that did not contain gamma-aminobutyric acid (GABA). O-Outcome: Evaluation items Main outcomes:Systolic blood pressure, diastolic blood pressure S-Study design: Research design The research designs used in the literature were randomized parallel group controlled trials (RCTPs), randomized crossover trials (RCTCOs), and quasi-randomized controlled trials (quasi-RCTs). In addition, the languages of presentation were documents written in Japanese and English. As a general rule, the presentation format will be an original paper, and papers in the form of short reports or summaries will also be accepted if the content can be specified. Abstracts of academic conference presentations (conference minutes) were excluded because their descriptive content was considered insufficient. There was no question as to whether or not the journal in which the article was published had been peer-reviewed. To avoid publication bias, we also included studies with results published in clinical trial registry databases. Regarding gray literature, we decided to use doctoral theses, reports from government agencies, think tanks, etc. whose detailed contents could be identified.
