Adjusted for age, sex, height, asbestos exposure and smoking history. Quartile 1: Carotene concentrations lower than 0.45 μmol/L; Quartile 2: concentrations more than 0.45 and less than 0.8 μmol/L; quartile 3: concentrations more than 0.8 and less than 1.3; and quartile 4: concentrations equal or greater than 1.3 μmol/L. | |||||
