Figure 1.

Effects of demographics and obesity on apnea–hypopnea index (AHI) (A) and primary endotypic traits (B–D) in the MESA study (Multi-Ethnic Study of Atherosclerosis). Squares and horizontal lines indicate the strength of each association (β with 95% confidence interval). Reference group for race/ethnicity is White. Note that the nonlinear scaling for AHI is due to the square root transformation; results were back transformed for interpretability. BMI = body mass index; SD = standard deviation.
