5. Predictive value of the A/N ratio in diagnosing OSAHS
An A/N ratio ≥0.825 was determined to be an independent predictor for
OSAHS. The area under the receiver operating characteristic curve (AUC)
was 0.659. The sensitivity, specificity, positive predictive value
(PPV), and negative predictive value (NPV) at this cut-off value were
45.1%, 80.9%, 64.3%, and 66.2%,
respectively. The accuracy was 65.6%.(Table5)
