- Long follow-up periods (ranging from 6.3 to 8 years) enhance the reliability of the findings.
- Limitations include potential confounding factors and the generalizability of results to broader populations.
- Further research is needed to explore the mechanisms underlying the observed effects and to assess the impact of vitamin E supplementation in diverse populations.
