Change in level and trend of substance use treatment utilization associated with a non-fatal opioid overdose

	Outpatient substance use services			Buprenorphine
	Slope	Standard Error	P-value	Slope	Standard Error	P-value
Baseline	3.76	0.61	<.0001	1.34	0.11	<.0001
Month	0.069	0.081	0.41	0.021	0.015	0.19
Post	5.94	0.77	<.0001	1.29	0.15	<.0001
Post * month	−0.55	0.12	0.0002	−0.037	0.022	0.12

Coefficients are from the interrupted time series analysis. The baseline indicates the intercept, the month coefficient is the slope of pre-overdose trend in the utilization rate, the coefficient of the post variable is the level of change in the utilization rate after the overdose, and coefficient of the interaction between the month and post variable is the change in trend of the utilization rate after the overdose.
