Nitric Oxide Metabolites and Lung Cancer Incidence: A Matched Case-Control Study Nested in the ESTHER Cohort

Figure 1

Dose-response relationship of a nitrite/nitrate concentration and lung cancer incidence, the ESTHER study (2000-2014). Notes: results of a logistic regression model adjusted for BMI, education, family history of lung cancer, asthma, physical activity, and vegetable and meat consumption frequency. In addition, potential confounding by the following factors was controlled by matching age, sex, smoking status, and pack-years of smoking. Knots: 10th, 30th, 50th, 70th, and 90th percentile. Solid red line: estimation for the odds ratio. Dashed grey lines: 95% confidence interval bands. Dashed green line: as reference.
