From: Utilization of the GOAL questionnaire as a standardized screening tool for obstructive sleep apnea
ROC curves of four screening tools (No-Apnea score, STOP-Bang questionnaire, NoSAS score and GOAL questionnaire) with an AHI cut-off ≥ 5 events/h. The area under the ROC curve (AUC) closer to 1 indicates the higher diagnostic accuracy of the screening questionnaire. AUC data are presented as values (95% confidence intervals). ROC receiver-operating curve, AHI apnea hypopnea index, AUC area under the curve.
