Abstract
A possible source of bias in the interpretation of chest films for pneumoconiosis is studied in the light of the UICC/ILO classification of pneumoconiosis into three subcategories. Theoretically, the percentage of subjects with the major categories of simple pneumoconiosis decreases with increasing category, and the percentage of subjects with each subcategory declines as one proceeds up the scale from 0/0 to 3/4. But in practice the phenomenon is not seen and more subjects are placed in the middle subcategories owing to the "middling" tendency.
