Changes in incidence, prevalence, and DALYs of testicular cancer in adolescents and young adults according to the determinants at the population level of population growth, aging, and epidemiological changes from 1990 to 2021. (a) At global, SDI regional level. (b) At GBD regional level. DALYs disability-adjusted life-years, SDI sociodemographic index. Black dots indicate overall percent difference, representing the percent difference in the numbers of incidence, prevalence, and DALYs between 1990 and 2021 (overall percent difference = [numbers₂₀₂₁−numbers₁₉₉₀]/numbers₁₉₉₀*100%). GBD regions are arranged from top to bottom based on SDI values, with lower values at the bottom.
