Data are from a sample of adults seropositive for severe acute respiratory syndrome coronavirus 2 in the Chicago area (n = 1101). Table created using the R package “Stargazer” (version 5.2.2). Coefficients statistically significant at P < .05 are shown in bold.
Abbreviations: IgG, immunoglobulin G; SE, standard error.
