A 1:2 matched case-control study was conducted in Wuhan area with conditional logistic regression model to study the relationship between occurrence of primary lung cancer and serum levels of beta-carotene. The results showed the lower the serum levels of beta-carotene, the higher the risk of lung cancer. It suggested the increase of serum beta-carotene with dietary intake could lower the risk of lung cancer.
在武汉地区开展了一项1:2匹配的病例对照研究，采用条件逻辑回归模型来研究原发性肺癌的发生与血清β-胡萝卜素水平之间的关系。结果显示，血清β-胡萝卜素水平越低，患肺癌的风险越高。这表明通过饮食摄入增加血清β-胡萝卜素水平可降低患肺癌的风险。
