Following publication of the original article [1], the authors reported an error. The incorrect sex-specific incidences of GCA were published. The correct mean annual cumulative incidence was 22.0 (95% CI 20.6–23.5) for women and 10.5 (95% CI 9.5–11.5) for men; p-value < 0.001 unaffected by the error. Revised versions of Fig. 2 and Table 2 are provided in this correction. Additionally, in the results section (page 4, first section) we report results of a sub-analysis of an extended cohort (n = 881). The correct annual cumulative incidence for women in this group was 24.1 and for men 11.6.

Annual cumulative incidence of giant cell arteritis (American College of Rheumatology (ACR) criteria fulfilled) in Bergen health area 1972–2012. Overall and ESR-specific cumulative incidence calculated as cases per 100,000 general population over the age of 50 years. Incidence by sex was calculated per 100,000 women or men, respectively, and incidence by the different age categories was calculated per 100,000 population of the same age categories (< 60 years, 60–69 years, 70–79 years and 80+ years). Points plotted represent raw incidence. Solid lines were estimated using the smoothing technique of a moving average of 5 years. ESR, erythrocyte sedimentation rate
