However, it was modest and not significant. Also, among women, neither cases nor controls were assigned to high probability or intensity of exposure to asbestos. Seventeen male cases and three controls had high probability of exposure to asbestos, which was therefore associated with a 62-fold increase in risk of peritoneal cancer.

All were white men. Although our matrix classified other occupations in the high probability of exposure, the excess was entirely driven by insulators. Most insulators worked in the construction industry (13/17), two in electric utility companies, and one each in manufacturing of industrial chemicals and in an unspecified manufacturing industry.

Among other occupations in the construction industry, risk was not elevated for supervisors and carpenters, and small non-significantly elevated risks were observed for construction laborers and painters.

A fivefold increase in risk was associated with high intensity of exposure to asbestos. Cross-classification of study subjects by exposure probability and intensity did not add much further information, because of small numbers and empty cells.
