RESEARCH QUALITY ASSESSMENT:
- All studies were randomized controlled trials, enhancing the reliability of the findings.
- Sample sizes varied, with some studies having relatively small cohorts, which may affect the generalizability of the results.
- The studies focused on specific populations (e.g., menopausal women, children with ADHD), limiting the applicability to broader groups.
- Further research with larger, more diverse populations and longer follow-up periods is needed to confirm these findings and assess long-term effects.
