Page 3606 1 Basically have two answers, but remember, 2 the four studies are case control studies, so the 3 cases of mesothelioma actually came from different 4 places. Either in the United States, in Canada, in 5 Germany and so on. 6 And these people, as I said, and I emphasize 7 over and over again, these cases include garage 8 mechanics who work in the 1920s, '30s and '40s. 9 Q And in relating those cases to the 10 population for purposes of determining if there was an 11 increased incidence of mesothelioma, they just looked 12 at the background level of mesotheliomas, correct? 13 A No. They compared to the percentage of 14 controls who work as garage mechanics. We are talking 15 about a case control study, not cohort study. 16 Q And what was the rate of mesotheliomas in 17 the controls? 18 A In a case control study we don't talk about 19 the rate of mesothelioma. We compare the percentage 20 of cases being garage mechanics compared to the 21 percentage of controls.
