Subsequent atypical hyperplasia or endometrial carcinoma presented in all women with non-atypical hyperplasia (left) and according to WHO 1994 classification type of non-atypical hyperplasia (right). The endpoint was atypia or carcinoma. Women were censored (black lines) due to hysterectomy, follow-up biopsy, or death. The women in whom follow-up biopsies were not obtained or in whom the biopsy material obtained was insufficient for diagnostic evaluation were censored on the day of their follow-up clinical examination.
