Primary Outcome Measures :
  1. Association between asbestos exposure and IPF [ Time Frame: 2 years ]
    estimated using logistic regression for any vs no asbestos exposure and adjusting for age and smoking status


Secondary Outcome Measures :
  1. Dose-response relationship between asbestos exposure and IPF [ Time Frame: 2 years ]
    estimated using logistic regression for categories of cumulative exposure and adjusting for age and smoking status

  2. Gene-environment interaction (for MUC5B rs35705950 and asbestos exposure) odds ratio. [ Time Frame: 2 years ]
    MUC5B rs35705950 and asbestos exposure odds ratio.
