Effect of 15q25 Locus (rs16969968 and rs57876) and 19q13 Locus (rs7937 and rs4105144) on the Risk of Lung Cancer

ORs and 95%CIs for the risk of lung cancer are calculated applying conditional logistic regression adjusted for quintiles of cotinine levels/CPD/duration of smoking. Effect of SNPs in smoking strata (current, former and never smokers) was calculated using unconditional logistic regression adjusted for matching variables (date of birth, country, date of blood collection and gender).
