Univariate and multivariate logistic regress analysis of the association of potential risk factors with poor treatment outcomes in MDR- and XDR-TB patients^*.

TB = tuberculosis; MDR = multidrug-resistant; XDR = extensively drug-resistant. OR = odds ratio. CI = confidence interval. *Variables included in the univariate analysis were shown in Table S1; All variables with a P value<0.2 in the univariate analysis were included in multivariate logistic regression analysis; 472 MDR-TB patients and 44 XDR-TB patients were included in multivariate logistic regression analysis. A P value of <0.05 was considered to be statistically significant. **n = 477 for MDR-TB; n = 44 for XDR-TB.
