Abstract
Using graphical representations to compare undistorted information it was attempted to bridge the gap between medicine and concerned risk-groups. Age-standardized mortality rates in 1979-1983 for 55 occupational groups (in 11 categories) of males aged 35 to 74 years were computed and compared to the Swiss national average; simultaneously the quantitative importance and the total mortality without accidents is shown for each occupational group: as an example the figure for lung cancer is reproduced. The elevated total mortality in the upper tertile of occupational groups is significantly explained by an increased risk of dying from circulatory or respiratory diseases, liver cirrhosis or malignancies of the lung, oropharynx, oesophagus or stomach. Foreseeable decrease of high-risk occupational groups will result in a further decline in mortality due to stomach cancer and cerebrovascular diseases in Switzerland.
