AHI, apnoea–hypopnoea index from the polysomnogram; AUC, area under the curve; ODI, oxygen desaturation index; RDI, respiratory disturbance index from the ApneaLink Plus; ROC, receiver–operator characteristic; subscript MAN is for manually scored, RAW for computer-reported raw value, SOX for stand-alone oximeter.
