Table 3.

Hazard ratios (HRs) and 95% confidence intervals (CIs) of time to second dose, median number of days to second dose, and non-adoption rates of the second dose by the end of study by racial and ethnic group, N = 5985.

	Time to 2nd Dose HR (95% CI)	Median Number of Days (95% CI)	Non-Adoption Rates (95% CI)
White Americans	1	156 (149, 166)	38% (18%, 58%)
Black Americans	0.65 (0.55, 0.78)	N/A (N/A, N/A)	58% (52%, 63%)
Hispanic Americans	0.77 (0.65, 0.91)	N/A (171, N/A)	52% (46%, 58%)
Asian American and Pacific Islanders	1.17 (0.96, 1.42)	149 (137, 161)	33% (24%, 41%)
Other	0.71 (0.54, 0.94)	N/A (151, N/A)	54% (43%, 64%)

Note. Except the Hispanic group, all listed racial and ethnic groups are non-Hispanic. HR results should be interpreted with caution, as the proportional hazard assumption did not hold (p = 0.0098). N/A = median survival not reached.
