Association of asthma severity and OSA
Post-hoc analyses revealed that participants with moderate to severe persistent asthma had twofold higher odds of having OSA compared to those with mild persistent and intermittent asthma, which was nominally significant in the unadjusted model (OR=1.97, 95% CI=0.97 – 4.116,P =0.064) and statistically significant in the model adjusted for age, sex and BMI z-score (OR=2.45, 95% CI=1.10 – 5.69,P =0.031), Table 4 .
