Odds ratio and 95% confidence interval for association of markers of Se status and polymorphisms in selenoprotein genes with advanced and high-grade prostate c cancer in the EPIC-Heidelberg nested case-control study.

Logistic regression adjusted for matching factors (age and time of blood collection) and family history of prostate cancer, participation in PSA testing, smoking status, and vigorous physical activity. Data was stratified according to disease stage. Pinteraction = P value of test for interaction between genotype and serum selenium concentration per 10 mg/l, serum SePP concentration (mg/l) or serum GPx3 activity per 100 U/l.
