text: Specific and strong connections between**a risk and an outcome (risk pairs)**are**covered by**
  **occupational disease recognition schemes**in the EU Member States. 177 Some countries have 
  opening options in their list systems, that is, in principle every disease with a dominant cause in working 
  conditions can be recognised. However, many court cases about the recognition of occupational 
  diseases demonstrate that a clear cause-effect relationship is not always evident, that is, due to missing 
  workplace exposure data from the past or competing causes in private circumstances. All occupational 
  diseases with a principally unambiguous relation between cause and consequence account only for a 
  small percentage of all**work-related diseases**.178 
  
  We can observe a**decrease of some of the major recognised diseases**, 179 either triggered by 
  preventive measures or triggered by shifts of workforce to sectors with less recognised occupational 
  diseases. The**new experimental EODS Statistics of Eurostat**180 documents the following 
  developments of recognised occupational diseases.
