.
1 Standardized to the smoking distribution of all with valid pulmonary function test. (Smokers, 31.6%; Ex-smokers, 42.4%; Non-smokers, 26.0%)
The categorization of work activity is such that an individual in a given category would have no exposure of a category lower in the table, i.e, a person classified as a brake worker would not have ether exposure to asbestos or other dusts. On the other hand, categories low in the table, shipyard workers, e.g., could also have exposure to asbestos in categories higher in the table, such as brake work.
