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 .
