Classification of the results of the random forest model for screening moderate to severe and severe risks of OSA by using the testing data set.

Categorical Variables	Moderate-to-Severe OSA Model	Severe OSA Model
	AHI ≥ 15 (N = 513); AHI < 15 (N = 188)	AHI ≥30 (N = 315); AHI < 30 (N = 386)
Precision %	85.74	67.72
Recall %	94.93	74.6
Accuracy %	84.74	72.61
F1 Score %	90.1	71.0
AUC, % (95% CI)	89.58 (87.44–92.01)	80.07 (77.05–82.80)

Abbreviations: AHI, apnea–hypopnea index; AUC, area under the curve; CI, confidence interval.
