From: Incidence of giant cell arteritis in Western Norway 1972–2012: a retrospective cohort study
Comparison of giant cell arteritis (GCA) incidence in our cohort with reported incidence from adjacent countries and key studies on GCA time trends. The mean annual cumulative incidence in the present study is shown as a moving average of 5 years. The mean annual incidences from other studies are shown as several means for separate time intervals of varying length. Data chosen for comparison are from Italy 1986–2012 [14], Israel 1990–2009 [39], Minnesota (USA) 1950–2009 [9], Finland 1970–1989 [46], Sweden 1997–2010 [29] and Norway 1992–1996 [11]
