Sensitivity, specificity, positive and negative likelihood ratio, and predictive value of ApneaLink plus clinical data for the prescription of CPAP.

AUC-ROC (SE)	Sensitivity (CI 95%)	Specificity (CI 95%)	+LR	−LR	+PV (CI 95%)	−PV (CI 95%)
0.953 (0.026)	90.6 (75–98)	100 (54.1−100)		0.094	100 (87.7−100)	67 (30−92.5)

AUC-ROC: area under the ROC curve; SE: standard error; + and −LR: positive and negative likelihood ratio; + and −PV: positive and negative predictive value.
CI 95%: confidence interval 95%.
