	Waiting time from contact to appt. (baseline)^**	Waiting time from contact to appt. (months 12-15)^**	Number of callbacks required to schedule appt. (months 16- 24)^***
Mean	7.26	5.81	0.47
Std Dev.	7.03	6.26	0.59
Minimum	0.00	0.00	0.00
1^st quartile	2.25	1.50	0.11
Median	5.00	3.25	0.33
3^rd quartile	10.25	7.88	0.67

Of the 201 clinics enrolled in the study, 4 were excluded for missing data and 5 were excluded because they worked exclusively with criminal justice or prison populations, making the patient profile and phone access process inappropriate.
