Extent of disease, cavitation, bacteriology, and drug susceptibility pattern among defaulters and nondefaulters.

Drug susceptibility:

 Resistant to one first-line drug9 (8.2)27 (8.2)
 Resistant to more than one first-line drug4 (3.6)8 (2.4)
Multiple drug resistance:4 (3.7)1 (0.3)0.01

There were no statistical significant differences between cases and controls regarding the extent of disease, presence of cavitation, or positive bacteriology ( ).
Whereas the proportion with resistance to one or more drugs was similar between cases and controls, the proportion with MDR was higher among cases (3.7) than among controls (0.3). Four patients with MDR who defaulted were still culture positive and one of them was also smear positive at the time of default.
