Factors thought to be related to lung cancer include smoking, radon, and educational attainment. These factors were analyzed in the present ecological study for Oregon with correlation and linear regression statistics. A moderate, inverse, and statistically significant correlation was found with educational attainment while surprisingly, negligible and statistically insignificant correlations were found with smoking and radon. More rigorous research such as case-control study designs, are indicated to verify or refute these findings.
被认为与肺癌有关的因素包括吸烟、氡和教育程度。本研究采用相关和线性回归统计方法,对俄勒冈州进行了生态研究。研究发现,教育程度与肺癌呈中度、负相关,且具有统计学意义,而令人惊讶的是,吸烟和氡与肺癌呈微不足道的、无统计学意义的负相关。需要进行更严格的研究,如病例对照研究设计,以验证或反驳这些发现。
