a
P = 0.001 (Kruskal-Wallis P value for comparison of median ages).
b
Eligible patients were at least 18 years of age, had AFB-positive sputum smears, and lived within a 30-min drive of the study area. In parentheses is the proportion of eligible patients who had both the DNA fingerprint pattern and interview completed.
c
The main analysis presented in this paper is for the three sites (Kanye, Lobatse, and Francistown) at which the majority of eligible patients were enrolled.
