Effect of selenoprotein SNPs on breast cancer risk after stratification of data according to tumourgrade and histology.

Adjusted values were analysed by conditional logistic regression. Odd ratios (95% confidence interval) and p-values are presented for each genotype. Significant results are presented in bold and italic.本研究采用条件logistic回归（conditional logistic regression）对经校正后的数值进行分析。针对每种基因型，均给出了比值比（Odds Ratio，95%置信区间）与p值；具有统计学显著性的结果以粗斜体格式呈现。
