  • Univariate and multivariate logistic regression models were used to calculate odds ratios (ORs) with 95% confidence intervals (CI) and establish the primary determinants of the most costly OSA patients. AHI: apnoea/hypopnoea index; BMI: body mass index; HPL: hyperlipidaemia; CVD: cardiovascular disease; t90: sleep time with an arterial oxygen saturation of <90%; NI: not included.
