The AUC of oximetry (0.89, 95% CI 0.82–0.97, P < .001) was higher than that of the STOP-BANG (0.73, 95% CI 0.60–0.86, P = .002) and Berlin (0.61, 95% CI 0.47–0.75, P = .129) questionnaires and the ESS (0.59, 95% CI 0.44–0.74, P = .231). AUC = area under the curve, ESS = Epworth Sleepiness Scale, ODI = oxygen desaturation index, ROC = receiver operating characteristic.
