Results from mixed effects logistic regression models using generalized estimating equations for professional referral versus non-professional referral by racial and ethnic group in participants with an MRI scan. Adjusted for age, gender, education, visit year, and CDR with a random effect for study site

	All participants			Mild cognitive impairment or dementia
	(n = 5,318)			and a global CDR or 0.5 or 1
				(n = 2,329)
Racial-Ethnic Group	Odds Ratio	95% CI	p	Odds Ratio	95% CI	p
Hispanic	0.84	0.68–1.04	0.1021	0.84	0.60–1.17	0.2973
Non-Hispanic Asian	1.05	0.57–1.93	0.8742	0.93	0.49–1.75	0.8206
Non-Hispanic Black	0.97	0.79–1.18	0.7376	0.82	0.51–1.34	0.4349
Other race	0.97	0.61–1.55	0.9067	1.40	0.62–3.15	0.4209
Non-Hispanic White	1.00	reference	–	1.00	reference	–

Reference group = non-professional referral. CDR = clinical dementia rating scale, professional = referrals made by healthcare professionals, non-professional=self, family and friends. Other race = American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and remaining multi-racial participants who did not also identify as non-Hispanic Black or non-Hispanic Asian.
