Model I: Adjusted for age, body mass index, ethnic, smoking status, dust exposure time, pneumoconiosis stage.
Model II: Model I with additional adjustment for chronic obstructive pulmonary disease, tuberculosis and hypertension.
MPV, mean platelet volume; PCT, plateletcrit; PDW, platelet distribution width; PHD, pulmonary heart disease; PLT, platelet count; RDW, red cell distribution width; WCC, white cell count.
