The Danish Quality Database for Cervical Cancer Screening

Figures & data

Figure 1 Danish cervical cancer incidence (red curve) and mortality (green curve) 1943–2013 (0–85 years of age).

Notes: Age-standardized rate per 100,000 (Nordic standard population). In 1967, start of first organized county-based screening program; 1986, first national guidelines issued; 2007, new national guidelines issued; and 2012, updated national guidelines issued.

Notes:

a In 2012, the number of annual cytology samples per screening laboratory was changed from 15,000 to 25,000.

b In 2011, the diagnostic sensitivity was changed from 60% to 70%.

c Age-standardized incidence per 100,000 (standard: Danish women 2005).

Abbreviations: ASCUS, atypical squamous cells of undetermined significance; HPV-triage, human papilloma virus triage; NR, no registration.
