  1. N.B. Cases with a histological record that is coded as ‘no diagnosis’ (average of 1.2% of total cases) are included in the denominator but not presented in the table. Please refer to Additional file 1 for a comprehensive explanation of age group criteria
  2. *These women are referred for colposcopy, but no follow-up examination has been registered in PALGA. These women are either lost to follow-up or only colposcopy is performed
