Re: Causal analysis of the impact of serum 25-hydroxyvitamin D levels on laryngeal cancer

Key Points

• Laryngeal cancer appears significantly associated with lower serum 25-hydroxyvitamin D levels.
• A 20% increase in vitamin D levels correlates with reduced laryngeal cancer risk among participants.
• Causal analysis based on health records across diverse populations indicates strong correlations.
• Findings highlight a potential avenue for preventive strategies in laryngeal cancer management.
