Univariate and multivariable analyses of factors associated with TST/IGRA discordance in household contacts.

Values are mean [Standard deviation] or n (percent), unless otherwise specified.P-values are calculated using a logistic regression model fit with generalized estimating equations (GEE) approach.AFB = Acid fast-bacilli; CFU = Colony forming units of M. tuberculosis in aerosols.Missing data: Index case HIV status (3), chest radiograph (22, 20 concordant and 2 discordant), contact HIV history (52), and meals shared with index case (1).1Univariate and multivariable model adjusted for correlation between contacts with the same index case using a GEE model. The final adjusted model only uses those that had p2 Visual analog scale is per unit increase.3 Cough peak flow is per 10 L/min increase.Univariate and multivariable analyses of factors associated with TST/IGRA discordance in household contacts.
