AIDS: acquired immunodeficiency syndrome; ART: antiretroviral therapy; HBV: hepatitis B virus; HCV: hepatitis C virus; InfCareHIV: National Quality Registry for HIV; SSOPHIE: Stochastic Simulation model of Outcomes of People with HIV In Europe.

^a Surveillance reports for AIDS from 1980–84 were reregistered after availability of HIV testing in 1985.

^b Possible under-reporting after 2005 is compensated by factoring in 15% in the model.

^c For heterosexual migrants from sub-Sahara, data source 1 covered 1988–2006 and data source 2 covered 2007–13.

^d CD4+ cell counts in these formats were used only for the whole population.
