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
