  • Greyed out cells were not included in respective models either due to collinearity or demonstration of statistically significant mediation towards likelihood of SARS-CoV-2 positivity.

  • Bold text in table represent the fully adjusted estimates for association between race/ethnicity and SARS-CoV-2 positivity

  • *Hosmer-Lemeshow goodness of fit p value: 0.58 and 0.73 (H0: model fit is correct).

  • †OR (95% CI) represents the direct association adjusted for all other covariates in the model.
