  1. Residential proximity to the spill is defined as living in or adjacent to a county or parish with coastline that was oiled during the spill
  2. aTotal number of observations included in the adjusted model
  3. bRisk ratios (RR) adjusting for age, gender, BMI, education, residential proximity to the oil spill, and smoking
  4. cModels adjust for duration of clean-up work in addition to the confounders age, gender, BMI, education, and smoking
  5. dModels adjust for duration of clean-up work in addition to the confounders age, gender, BMI, education, smoking and residential proximity to the oil spill
