Background and objectives: The role of medical papers in different disciplines in men’s health has not been well-clarified. The aim was to study qualitatively and quantitatively the impacts of medical papers in different disciplines of medical science on men’s health. Materials and methods: The data have been analyzed by combining correlation analysis, principal component analysis, and multivariate regression methods. This combination method can clean input data by using its correlation with the target data. Thus, the weight of an input parameter by using the multivariate regression method can be obtained. Thus, the proposed method is used to perform personalized optimization. Results: 69.3% of the variation (p < 0.01) in the male mortality rate of China can be explained by the first principal component. 75.8% of the variation (p < 0.01) in the male life expectancy at birth in China can be explained by the first and the second principal component. Conclusion: The published medical papers in different disciplines, education, income, and GDP have equally important effects on men’s health. |
