Causal role of immune cells in obstructive sleep apnea hypopnea syndrome: Mendelian randomization study

Figure 1 Overview of this bidirectional mendelian randomization study design. AC: Absolute cell count; MR: Mendelian randomization; SNPs: Single nucleotide polymorphisms; OSAHS: Obstructive sleep apnea hypoventilation syndrome; GWAS: Genome-wide association studies; RC: Relative cell count; MP: Morphologic parameters.

Figure 2 Forest plots showed the causal associations between immune cell traits and obstructive sleep apnea hypoventilation syndrome by using different methods.

Figure 3 A diagram illustrates both cell subpopulations in the airways of patients with obstructive sleep apnea-hypopnea syndrome that are involved in inflammation.
