  1. 1Model 1: the association between days having more than 5 drinks and a >2 CAGE score.
  2. 2Model 2: the association between age and a >2 CAGE score.
  3. 3Model 3: the association between length of employment and a >2 CAGE score.
  4. 4Model 4: entered into the model were all three independent variables (more than five drinks, age, employment), and the association to a >2 CAGE score was explored.
