Factors associated with the probability of passive case detection by HIV-status, adjusted for cough, ability to work and smear-status in all PTB patients (n = 282), smear-positive patients only (n = 123), and patients reporting a cough for more than 2 weeks (n = 198).

CI = Confidence interval PTB = pulmonary tuberculosis. Missing variables (see table 1 and 2) were multiply imputed before logistic regression. *Not all effects reach statistical significance in the small group of smear-positives, but the full model is shown to show trends.
