		Patients with OUD	Patients without OUD	Total
Cut point on the 0-2 and 3+ sample	3+	181	58	239
Cut point on the 0-2 and 3+ sample	0-2	31	330	361
Total		212	388	600
Value	Formula	Values	Result	95% Confidence Interval
Sensitivity	A/(A+C)	181/212	0.854	0.799-0.898
Specificity	D/(D+B)	330/388	0.851	0.811-0.885
PPV	A/(A+B)	181/239	0.757	0.709-0.799
