[Correlation between selenium levels in the human body and lung cancer. II. Multi-statistical analysis of the correlation between selenium levels in the blood, hair, lung and lung cancer].
18 factors, including possible lung cancer-causing factors and body selenium (Se) levels, were analyzed by computer-based multiple stepwise regression and main component analysis. 1. The results indicated that Se levels in blood, hair and lung had correlation with lung cancer to some extent. 2. The correlation of blood and lung Se was the most significant one, the significance of which was only second to age and smoking habits. The standardized regression and factor load coefficients showed a negative correlation with blood Se level and a positive one with lung Se level, which corresponded with the results obtained by the single factor analysis.
