SBQ demonstrated limited performance for moderate-severe OSA (sensitivity\u2009=\u200952%, specificity\u2009=\u200962%, AUC\u2009=\u20090.600) and severe OSA (sensitivity\u2009=\u200918%, specificity\u2009=\u200987%, AUC\u2009=\u20090.577). Oximetry was satisfactory for moderate-severe OSA (sensitivity\u2009=\u200967%, specificity\u2009=\u200973%, AUC\u2009=\u20090.769) and severe OSA (sensitivity\u2009=\u200950%, specificity\u2009=\u200988%, AUC\u2009=\u20090.730). The diagnostic performance was improved with new cut-offs at ODI-Ox\u2009\u2265\u200911 for AHI-PSG\u2009\u2265\u200915 and ODI-Ox\u2009\u2265\u200920 for AHI-PSG\u2009\u2265\u200930.
