Measuring disease
An international collaborative study was made of the results of treatment of new cases of pulmonary cases that were smear positive. Of 492 cases in British Columbia, Canada, 5.1% died during the course of their treatment as compared with 3.0% of 3,163 cases in Sudan. The same definitions for outcome of treatment were used, following the recommendations of the IUATLD.

-
What other information would be necessary to compare the deaths in the two countries?
-
How would this information be used to improve the validity of the comparison?
