*Significant [X2(3) = 8.76, p = 0.033] between missing data status and race/ethnicity; however, the contingency coefficient (C = 0.10) showed that the association was small. Hispanic participants [OR = 1.7 (1.1, 2.7)] and Other race/ethnicity participants [OR = 1.9 (1.0, 3.6)] were significantly more likely to have missing SE data
