1 mentioned that you wrote to the author of one paper. Page 3594 2 Have you ever written to these authors 3 asking them or suggesting to them that their verified 4 cases of asbestosis weren't really asbestosis? 5 A No, I have not. 6 Q They say it is noteworthy, however, that 7 past exposures during brake maintenance probably have 8 been heavier than the concentrations reported in this 9 study. Thus, the present exposure may indicate a 10 lowered risk of asbestosis in the future. 11 What do you understand that to mean? 12 A That means the exposures in the past of 13 garages, because the work practice might have been 14 higher, the exposure. And that is the reason why I 15 rely on those case control studies, because those case 16 control studies would include garage mechanics who 17 work in the 1920s, 1930s and 1940s. 18 It would not be appropriate today to start a 19 study, a cohort study of garage mechanics exposed 20 today and use that study to form an opinion of garage 21 mechanics who were exposed in the 1950s and 1960s.
