This more recent analysis by Hodgson and others modelled the expected burden of mesothelioma mortality in Great Britain based on male mesothelioma deaths from 1968 to 2001 as a function of the rise and fall of asbestos exposure during the 20th century and took into account the difference between fibre types. The models fitted the data to predict exposure patterns compared with the actual exposure patterns based on imports of amosite and crocidolite. The authors now state that chrysotile had zero weight in both the models they constructed. This means that, based on their work, the mesothelioma cases in Great Britain since 1920 can be explained by exposure to a combination of amosite and crocidolite.
