The joint effect of cumulative smoking dose with IGF1 (CA)n repeat, IGF2 820, IGFBP3 -202 genotypes for lung cancer risk.

Data were matched by age and gender, calculated by multiple conditional logistic regression and adjusted for green tea consumption, exposure to fume of cooking, and family history of lung cancer.1P2P = 0.08,3P = 0.03; P value was adjusted by multiple testing (bonferroni correction).

数据按年龄及性别进行匹配，采用多条件logistic回归进行统计计算，并对绿茶摄入量、厨房油烟暴露情况及肺癌家族史进行校正。1P2P=0.08、3P=0.03；P值经多重检验（邦费罗尼校正，Bonferroni correction）校正。
