Correlations between HSBP-related mortality and DALY rates and SDI and EAPC. a, c Correlations between mortality (a) or DALY (c) rates and SDI in 2021. b, d Correlation between EAPC of mortality rate (b) or DALY rate (d) and SDI in 2021. e, f Association between the rates of HSBP-related deaths or DALY and SDI (1990–2021) across 21 regions. For each region, the points from left to right depict the estimates for each year. The solid blue line represents expected values across the SDI spectrum. e Mortality rate. f DALY rate. DALY, disability-adjusted life year; EAPC, estimated annual percentage change; HSBP, high systolic blood pressure; SDI, sociodemographic index
