Linear regression between wait time or length of visit and by race/ethnics, NHAMCS 2005–2016.

	Wait time		Length of visit
	Beta (95% CI)	p-value	Beta (95% CI)	p-value
White	Reference (1)		Reference (1)
Black	0.190 (0.157–0.224)	<0.001	0.138 (0.123–0.152)	<0.001
Hispanic	0.178 (0.141–0.214)	<0.001	0.173 (0.157–0.189)	<0.001
Asian	−0.018 (−0.102–0.065)	0.665	0.010 (0.063–0.137)	<0.001
Other	0.068 (−0.046–0.183)	0.242	0.003 (−0.024–0.080)	0.287

The model was adjusted for the following factors: demographics (gender, age group), socioeconomic (residence type, insurance type, census region), visiting and clinical (year, week of day, arrival by ambulance, seen within last 72 h, pain level, temperature, heart rate, dialytic blood pressure), and ESI score. The betas are the coefficients between the log (wait time or length of visit) and the racial/ethnic group.
