  1. The data in this table are based on new sputum smear positive patients of whom a control sputum smear was available after 2 months of intensive treatment. One site did not register any new cases during the study period and was not included in the results in this table. a The natural log of the number of newly registered PTB cases was used as weight in the regression analysis. b Based on the log likelihood ratio.
