Strategies are recommended to enhance the quality of MR studies in sleep medicine, including collaborations between MR experts and sleep specialists.The paper also explores sleep medicine-specific issues like analyzing binary traits and addressing heterogeneity in pooled analyses.Guidance is provided on transparent reporting of MR findings, stressing the need for comprehensive effect estimates, confidence intervals, and p-values.We conclude by advocating for rigorous MR implementation in sleep research to deepen our understanding of sleep-health relationships.By following best practices in study design, analysis, and reporting, researchers can reinforce the credibility and impact of MR findings in sleep medicine, ultimately improving patient care and read more public health strategies.
