We repeated all secondary analyses reported in our online supplementary tables S1 and S2 by using the same reference as in our main analysis (table 1). Risk estimates by exposure category are consistent with our main analysis results (see table 2 of our paper), confirming the exposure–response trend for pleural malignant mesothelioma irrespective of the route of exposure (occupation or environment). Owing to space constraints, we are only showing our new results for occupational and environmental exposures, but … ER -
