Distributions of cases and controls from the Environment And Genetics in Lung cancer Etiology study and associations of lung cancer with lung disease diagnosed at least one year prior, stratified by time since diagnosis of lung disease (latency).

*OR = odds ratio, CI = confidence interval. Adjusted for study age, gender, region, pack-years, amount of cigarette smoking, bronchitis (unless main effect or COPD), emphysema (unless main effect or COPD), and pneumonia.
†Does not sum to total due to missing values in multivariate analysis.
‡COPD = chronic obstructive pulmonary disease (chronic bronchitis and/or emphysema).
∥OR for females with asthma diagnosed 1–5 years prior  = 0.50 (95% CI = 0.09–2.9) and for asthma diagnosed >5 years prior  = 1.7 (95% CI = 0.75–4.0, LRT p-value  = 0.4).
