This study was conducted to evaluate the network scale-up method for estimating the sizes of groups most at-risk for HIV/AIDS. Using 4 different data sources, 2 of which were from other researchers, the authors produced 5 estimates of the number of heavy drug users in Curitiba, Brazil.

This data release includes:

  • 1 pdf file which contains documentation for the csv files and the R code
