Figure.. Small Opacity Profusion Classification by Large Opacity Category Among Chest Radiographs of Coal Miners at 3 Clinics in Virginia, January 2013-February 2017
aA case of PMF was defined as an International Labour Office classification of large opacity (any opacity >1 cm) category A (≥1 large opacities with combined dimension ≤5 cm), category B (≥1 large opacities with combined dimension >5 cm but not exceeding the equivalent area of the right upper lung zone), or category C (size greater than category B) pneumoconiosis. bSmall opacity profusion was classified into 4 categories (0, 1, 2, 3), with each divided into 3 subcategories (0/−, 0/0, 0/1, 1/0, 1/1, 1/2, 2/1, 2/2, 2/3, 3/2, 3/3, 3/+).
