RESEARCH QUALITY ASSESSMENT:
- All studies were randomized controlled trials or cross-sectional studies published in reputable journals.
- Sample sizes varied, with the largest study including over 2400 participants, enhancing the reliability of findings.
- Limitations include potential biases inherent in self-reported dietary intake and the need for longer follow-up periods to assess long-term effects.
- Further research is warranted to confirm these findings across diverse populations and to explore the mechanisms underlying the observed benefits of Vitamin B1.
