Meta-Analysis Data on Dietary Nitrate Effects for Weight Management

A systematic review and meta-analysis by Wenjun Cai, last updated in April 2026, aggregates data from 8 randomized controlled trials involving 199 adult participants with obesity. It evaluates the effects of dietary nitrate supplementation on outcomes including body weight, BMI, blood pressure, and lipid markers. The study adhered to PRISMA 2020 guidelines and is registered with PROSPERO.

Use Cases

• Re-analyzing effect sizes for systolic blood pressure based on reported standardized mean differences and confidence intervals.
• Investigating heterogeneity in lipid parameter outcomes based on reported I² statistics.
• Assessing publication bias for body mass index and diastolic blood pressure as noted in the results.
• Conducting subgroup analyses by intervention duration based on the described stratification.

Strengths

• Includes data from 8 randomized controlled trials, a defined study design.
• Reports specific statistical results, including standardized mean differences, p-values, and I² values for outcomes like systolic blood pressure and total cholesterol.
• Follows PRISMA 2020 reporting guidelines, suggesting a structured methodology.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small at 15.8 KB, reflecting a limited scope from only 199 total participants.
• Publication bias was detected for some outcomes, as noted in the results.
