Mixed effects logistic regression model evaluating odds of identified, confirmed and initiated^* for students in the universal and targeted screening arms

Outcomes	Randomized group	OR (95% CI)	p-value	Variance of random school effect (SE)
Identified	Universal screening Targeted screening (ref)	7.1 (5.7–8.8) 1	<0.001	0.08 (0.05)
Confirmed	Universal screening Targeted screening (ref)	7.8 (4.6–13.1) 1	<0.001	2.4 (1.2)
Initiated	Universal screening Targeted screening (ref)	4.0 (2.0–7.9) 1	<0.001	1.6 (1.0)

^*identified as at risk for suicide: positive Patient Health Questionnaire-9 (response >0 on item 9) or behavior prompting referral to Student Assistance Program (SAP) for suicide risk; confirmed: SAP does not diagnose, but to meet criteria, SAP must confirm identified behavior/symptoms warrant further evaluation; initiated: participated in at least one SAP recommended treatment/service, e.g., follow-up mental health supports

OR: Odds ratio; CI: Confidence interval; SE: Standard error
