Joinpoint regresson models were employed to calculate the annual percentage change (APC) and average annual percentage change (AAPC) to assess the temporal trends in the burden of SCI. Subsequently，age-period-cohort model analysis was conducted to evaluate the net effects ofage，period，and cohort on disease burden，and to predict the trends in the burden of SCI from 2022 to 2050.Results In 2021，the number of newly diagnosed SCI cases in China was 99，400，and the total number of cases was 2.7663 million， representing an increase of 43.27% and 63.27% ，respectively ......
