Receiver-operator characteristic (ROC) curve of the composite biomarker panel for obstructive sleep apnea (OSA).
(A) ROC curve for distinguishing adult OSA from subjects without OSA. ROC curves for combination of 4-hydroxypentenoic acid, arabinose, glycochenodeoxycholate-3-sulfate, isoleucine, serine and xanthine. (B) ROC curve for distinguishing adult OSA from subjects with simple snorers (SS). ROC curves for the combination of 4-hydroxypentenoic acid, 5-dihydrotestosterone sulfate, serine, spermine and xanthine.
