Figure 11. Co-evolution of age-standardized burden estimates with SDI globally and for GBD regions for female infertility from 1990–2017. (A). Prevalence (B) DALYs. Colored lines show global and region values for age-standardized burden estimates rates. Each point in a line represents 1 year starting at 1990 and ending at 2017. The black line represents the average expected relationship between SDI and burden estimates rates for female infertility based on values from each region in the 1990–2017 estimation period. DALYs = disability-adjusted life-years. SDI = Socio-demographic Index.
