Effect of the Interaction between Obstructive Sleep Apnea and Lipoprotein(a) on Insulin Resistance: A Large-Scale Cross-Sectional Study

Figure 1

Interaction between lgAHI and lgLp(a) on the relationship with lgHOMA-IR. As depicted, the relationship between lgAHI and lgHOMA-IR is modulated by the level of lgLp(a). With lgLp(a) declining (from the 90th to 10th percentile), a more steep and significant positive linear relationship between lgAHI and lgHOMA-IR could be observed, suggesting significant positive interaction. The P value was calculated with multivariable linear regression analyses adjusted for age, gender, BMI, waist-to-hip circumference ratio, MAP, current smoking status, current drinking status, TC, TG, HDL-C, LDL-C, ApoA-I, and ApoB.
