  1. Brazilian population in 2010: 190,731,964 inhabitants. Incidence rate per 100,000population. Small Cities< 50,000inhabitantsand density < 80 inhabitants/km2, medium cities population between 50,000 and 100,000 or density > 80 inhabitants/km2, large cities population > 100,000inhabitants
  2. Coefficients were calculated between the HDI/GI and % of cure, % lost to follow-up, % relapse, PTB incidence rate, AIDS incidence rate, and rate of deaths due to PTB (calculated by direct standardization)
  3. AIDS Acquired Immunodeficiency Syndrome, HDI Human Development Index, GI Gini Index
  4. aSignificant correlation at the 0.05level (2 tailed), bSignificant correlation at the 0.01 level (2 tailed)
