  1. a: When comparing the rates of stomach cancer mortality of born in 1965–1999 who without exposure to the famine with that of born in 1930–1964 who exposure to the famine, the Pearson Chi-square: 14.815, P < 0.001 for males, and that the Pearson Chi-square: 4.269, P = 0.039 for females, respectively. b: Standard mortality was calculated by the world population of National Office for Cancer Prevention and Control. 1980, and the unit was 1/100,000.
