Estimated associations (and their 95% CI) between the risk of cancer and the index of exposure to MSWIs (edf = degrees of freedom) for all cancers in women, breast cancer in women and lung cancer in men. Associations estimated (a) without covariates in the model and (b) adjusting for the covariates. The highest exposed IRIS (index of exposure > 0.16 = 95th percentile of the distribution of the exposed IRIS) are all exposed to the same incinerator, the incinerator of La Tronche in Isère. These IRIS have a small number of observed lung cancers in men compared to the expected number. The covariates included in the model do not fully explain this difference.
