Estimated number of people living with HIV by year using different estimation methods, Norway. Dashed line: ECDC HIV modelling tool using default model assumptions for CD4 distribution. Solid line: Spectrum using the CSAVR tool. Dotted line: Spectrum using incidence estimates from the ECDC HIV modelling tool using default model assumptions for CD4 distribution. Estimates exclude diagnoses among persons previously diagnosed in another country who were not reported to have died or out-migrated by the end of 2018. The Spectrum models incorporate previous positive cases in the PLHIV estimate through the assumption that migrants have the same HIV prevalence as the resident population
