Punitive laws, key population size estimates, and Global AIDS Response Progress Reports: An ecological study of 154 countries.

Introduction: UN global plans on HIV/AIDS have committed to reducing the number of countries with punitive laws criminalizing key populations. This study explores whether punitive laws are associated with countries' performance on targets set in the global plans.

Methods: The study used chi-square tests of independence to explore associations between legal status, key population size estimates, and HIV service coverage for 193 countries from 2007 to 2014.
