Data sources
The detail methods of GBD study (2019) have been reported in several studies.2,6,7 The data on incidence, mortality and DALYs were downloaded from the Institute for Health Metrics and Evaluation (IHME, http://ghdx.healthdata.org/gbd-results-tool). The codes used for GBD study analysis can be accessed through the following address: http://ghdx.healthdata.org/gbd-2019-code. In GBD study, all estimates were generated with 95% uncertainty intervals (95% UIs), which were determined based on the 2.5th and 9.75th percentiles of 1000 draw of the uncertainty distribution. The inclusion criteria were as follows: (1) the cause was “cervical cancer”, “uterine cancer”, and “ovarian cancer”; (2) the year was selected from 1990 to 2019 and the location was “China”; (3) “incidence”, “death” and “DALYs” were selected for measures.
The age-standardized rates for the incidence, mortality, and DALYs of gynecological malignancies were estimated using the World Health Organization (WHO) World Standard Population Distribution (2000-2025). For the prediction of burden, the predicted Chinese population was obtained from the United Nations World Population Prospects 2019 Revision, by year, sex and age (https://population.un.org/wpp/Download/Standard/Population/).
