Incidence rates per 100,000 population
Small Cities < 50,000 inhabitants and density < 80 inhabitants/km², medium cities population between 50,000 and 100,000 or density > 80 inhabitants/km², large cities population > 100,000 inhabitants. The variables cure, relapse, and lost to follow-up are provided as an average of percentages in the groups of cities
AIDS Acquired Immunodeficiency Syndrome, HDI Human Development Index, GI Gini Index
^aThe HDI and GI show the average by population group. ^bMortality rate due to PTBwas calculated by direct standardization
