Percentage of patients experiencing an adverse TB outcome analysed by poverty, education level, symptom duration, time too unwell to work, catastrophic costs, previous TB, and resistance profile.

<p>Error bars represent 95% confidence intervals. <i>p</i>-Values correspond to the association of each variable with adverse TB outcome in univariable logistic regression, except for poverty and symptom duration, which were analysed as continuous variables. In multivariable regression analysis, the following variables remained independently associated with adverse TB outcome: time too unwell to work (<i>p</i> = 0.02), catastrophic costs (<i>p</i> = 0.003), having had a previous episode of TB (<i>p</i> = 0.004), and currently having MDR TB (<i>p</i><0.0001).
