Data are presented as prevalence (95% confidence interval). #: prevalence was calculated from patients with a main or secondary hospital diagnosis of sarcoidosis and with the assumption of a normal life-span for females and males; ¶: only patients with a main diagnosis of sarcoidosis were included and it was assumed that two out of three cases will go into remission after a mean disease duration of 12 months and that one out of three cases will suffer from a chronically active disease.
