      <subfield code="a">The deaths from all causes in the Rhondda Fach between the two radiological surveys in 1950-51 and 1953 have been related to the age, sex, and occupation of those in the valley at the time of the first survey and compared with expected values derived from the Registrar General's figures for England and Wales. In the case of miners and ex-miners readiographed during the first survey, the deaths were also related to the category of pneumoconiosis found in their chest radiographs at that time. The results suggest that the more advanced forms of complicated pneumoconiosis, in the higher ages, may be associated with an excessive number of deaths. No such excess was found associated with simple pneumoconiosis, although the possibility of a small excess of deficiency could not be excluded</subfield>
