Unadjusted and Adjusted Odds Ratios of Index TB Case, Household Contact and Environmental Factors for Predicting High Mycobacterium tuberculosis Transmission Households.

1Household level data, except chest radiograph (see footnote E below), are modeled using logistic regression. Contact level data are modeled by using generalized estimating equations (GEE) approach to estimation for logistic regression with an independent working correlation matrix with standard errors obtained from a sandwich estimate of the variance.2Fit using a GEE approach to estimation for logistic regression with an independent working correlation matrix adjusted for all other covariates listed. Standard errors are from a sandwich estimator of the variance.3One participant whose SCG could not be distinguished between 5 or 6a was excluded.*Wald (pairwise vs. reference) P-value.+Global (omnibus) score P-value.E = denotes exact Odds Ratios and P-values using an exact test of the parameters from exact logistic regression.VACS = Visual analog cough scale; LCQ = Leicester cough questionnaire.BCG = Bacille Calmette Guérin vaccine; TST = Tuberculin skin test; OR = Odds ratio; CI = Confidence Interval.
