  • *The Reference Standard is defined as the majority diagnosis of the combined H&E and non-objectified IHC score, based on agreement on CIN grade in two out of three pathologists (see also the Methods section).

  • CIN, cervical intraepithelial neoplasia; IHC, immunohistochemistry; P, pathologist; SCC, squamous cell carcinoma.
