Figure 1 Overall worldwide prevalence ranges for SLE Figure 1 | Overall worldwide prevalence ranges for SLE. Reported SLE prevalence ranges per country (per 100,000 of the population) are shown, as denoted by the key. The number of studies (n =) indicate those from which each prevalence range was determined. Note the dual shading of Spain, indicating that the prevalence values span two neighbouring ranges.
