Decomposition analysis of the number of trachoma cases in China from 1990 to 2021.
The changes in the burden of trachoma disease in China from 1990 to 2021 are determined by demographic factors such as population growth, aging, and epidemiological changes. The black dots represent the overall changes in the contributions of all three components. For each component, a positive value indicates a corresponding increase in the burden of trachoma disease attributed to that component; Negative values indicate a corresponding reduction in the burden of trachoma disease caused by this component.
