Age-standardized incidence rate (A) and age-standardized death rate (B) of peripheral artery disease for 21 Global Burden of Disease (GBD) regions by Socio-Demographic Index (SDI), 1990–2019; expected values based on SDI and disease rates in all locations are shown as the black line. Thirty points are plotted for each GBD region and show observed rate from 1990 to 2019 for that region. The R indices and P-value were derived from Pearson correlation analysis.
