National trend of gastric cancer mortality in China (2003–2015): a population-based study

Age-standardized rates of mortality (ASRM) of gastric cancer in rural and urban areas in Chinese populations from 2003 to 2015. ASRMs of gastric cancer were estimated by using the 2010 Chinese Census population for the whole population (a), males (b), and females (c) in rural and urban areas. The scattered data points represent the observed ASRMs. The trend lines were estimated by modeling ASRMs from Joinpoint analysi
