To be noted, many countries of the world do not provide information on the prevalence of psoriasis. For these countries, without high quality original data sources, estimates were generated by extrapolation, making using of the psoriasis prevalence estimate of the region the country was nested in, grouped according to the United Nations classification. Therefore, extrapolated estimated are less reliable, than for countries with original data sources and should be interpreted with caution.
Please note, a publication will be available soon where all the countries with extrapolated estimates will be listed in a Table.
